The web app adds the icons (`src/lib/integrations.ts`) - `packages/db` - `@proxy/db`: Prisma 6 on Postgres. `src/index.ts` is the client; each module (`auth.ts`, `user.ts`, `organization.ts`, `connection.ts`, `info.ts`, `agent.ts`, `audit.ts`) exports functions returning `Result` through `wrapDb`. `relationMode = "prisma"`: no foreign keys in the database, so Prisma runs the cascades and every relation column has its own index.

Browser-called writes take `requireBrowserOrigin` (CSRF); routes that read a cookie have no CORS. `src/connections/` lists, deletes and sets defaults on an organization's connections, connects a mailbox with an app password after signing in to its IMAP and SMTP servers (`email/`), and connects Granola, Notion and Linear by signing in to their MCP servers (`mcp/`, shared by all three: OAuth with PKCE against the server's authorization server, a client registered for each sign-in so nothing is set up beforehand, the handshake in an encrypted cookie, `mcpConnectRoutes` making both routes; tokens are refreshed as they run out, one refresh at a time per connection on each server, and saved only over the ones they replace; each tool call is one stateless `tools/call`, `mcp-client.ts`). Granola's notes and transcripts are on by default, Notion's Read pages and Linear's Read issues alone; a Notion or Linear sign-in is for one workspace, and a Notion one lasts at most 180 days, however often it is refreshed. `src/agents/` makes, revokes and deletes agent logins (the password is sent once, only its argon2id hash is kept) and sets an agent's own settings per action of a connection where they differ from the default. `src/records/` reads and writes a collection's records through the integration's `Connector` (`connectors.ts`): Information's live in the database (`info-connector.ts`), a mailbox's are fetched over IMAP on every request (`email-connector.ts`), which merges the inbox and the folders the server marks as Drafts and Sent into one list (ids start with the folder: `inbox-…`, `drafts-…`, `sent-…`) and runs the commands: flags, moves to the folders the server marks as Archive (Gmail's All Mail) or Trash, and sending over SMTP, a draft or a new email, filing a copy in Sent where the server doesn't (Gmail does). Received emails are never edited or deleted for good; only drafts are. Granola's notes are fetched from its MCP server on every request (`granola-connector.ts`; the reading of the XML-like text Granola answers in is in `connections/granola/granola-mcp.ts`): its Notes and Transcripts collections are the same meetings by Granola's meeting id, and since Granola's tools have no pages, a page is 30 days of meetings; one that finds none skips back to the newest meeting before it, so the list ends where the meetings do. Granola's dates and attendees are shown as Granola writes them. Notion's workspace is fetched from its MCP server the same way (`notion-connector.ts`, the reading of its answers in `connections/notion/notion-mcp.ts`), as the person who signed in, as a tree in one nested collection: Notion has no list of every page, so the top is their Recents and a search (Notion's own, AI search where the workspace has it) finds the rest, one page of 50; inside a page are the pages and databases in its content, inside a database its saved views (`view-…` ids), or the rows of its only one, and inside a view its rows, paged with Notion's cursor (view queries have no plan quota; Notion's row and SQL queries do). A page reads as Notion-flavored Markdown, a row's properties beside it as "Name: value" lines (`notion-properties.ts`), and only a page's, database's or view's id is ever sent to Notion's fetch; a new page is a private draft at the top, or goes inside the page, database or view it is made in, a row's title in the database's title property; an edit sends the title, the properties written differently and the content, each only where it changed, and pages are never deleted. Notion's MCP server has no tool that deletes or trashes a page. Linear's issues are fetched from its MCP server the same way (`linear-connector.ts`, the reading of its answers in `connections/linear/linear-mcp.ts`), as the person who signed in, by their identifier (`ENG-123`): a list is the issues updated last first, 50 to a page with Linear's cursor, narrowed by the type of status (`?statusType=Started`) and searched in titles and descriptions, and an issue opens with its comments, oldest first. Teams, statuses, people, projects and labels are written by name, as Linear shows them and finds them, its refusals passed on to the agent; an edit sends only the fields written differently, an empty one clearing it. Linear's MCP server has no tool that archives or deletes an issue. Lists take `?search=` (only where the collection has a `searchHint`; Granola has none), `?filter=` (the collection's `filterField`, such as `?filter=Draft`), `?parent=` (only in a `nested` collection: the list inside a record, answered with its `trail`, the records above it; a record made there goes in it) and `?page=` (`list-query.ts`) and answer a page, newest first (a mailbox's 50 emails, Granola's 30 days), with the next page's token; a mailbox's token holds where each folder goes on, so paging through the merged list shows every email once, and its search uses Gmail's own syntax on Gmail (`X-GM-EXT-1`) and IMAP text search elsewhere. Agents sign in at `/agent-auth/login` with a cookie of their own (`src/agent-auth/`); `src/agent-side/` serves them: the connections an agent can use, the tools it has with each, and `runAgentTool` (`tools.ts`), the one place a tool runs, which checks it against the agent's access as it is now, validates its params against the tool's schema (an edit changes only the fields given), calls the connector and logs it, denied ones too, to the activity log that `src/activity/` lists. Over HTTP that is `/api/agent/me`, `GET /api/agent/connections/:id/tools` and `POST /api/agent/connections/:id/tools/:tool` with `{params}`; `src/mcp/` serves the same over MCP at `/mcp` (Streamable HTTP without sessions, JSON answers, no stream): four tools whatever the login may do, `list_connections` (the entry point), `list_tools`, `read` (only tools that read, marked read-only) and `run`, and server instructions naming the agent's connections. MCP clients sign in with OAuth 2.1 (`src/oauth/`), Personal Agent Proxy being its own authorization server: metadata under `/.well-known/`, Dynamic Client Registration at `/oauth/register` (open to anyone, each registration first deleting the clients that registered over a day ago and never finished a sign-in), `/oauth/authorize` sealing the request into the web app's `/connect-agent` page, where the person chooses the agent login the client works as or makes one, and `/oauth/token` with PKCE (S256 only) and refresh tokens replaced on every use; codes and tokens are kept as their SHA-256, and revoking an agent ends its clients' tokens. These endpoints take any origin (CORS), since none reads a cookie; credentials and Information records are stored encrypted with `ENCRYPTION_KEY` (`src/utils/secret-crypto.ts`).

Teams, statuses, people, projects and labels are written by name, as Linear shows them and finds them, its refusals passed on to the agent; an edit sends only the fields written differently, an empty one clearing it. Linear's MCP server has no tool that archives or deletes an issue. PostgreSQL and MySQL (MariaDB too) are two integrations on one code path: a database is connected with its host, port, database, user, password and encryption (`connections/sql/`: `route.ts` makes both routes per dialect, `sql-client.ts` opens one connection per request with `Bun.sql`, to the address `utils/host-check.ts` resolves the host to, refusing private addresses unless `ALLOW_PRIVATE_HOSTS` is set, and `sql-statement.ts` checks an agent's query is one statement that reads), and `records/sql-connector.ts` reads and writes it through `records/sql-dialect.ts`, where the two differ: the tables are one nested collection, a table holding its rows, a row read and written as "column: value" lines and found again by its primary key (ids `public.users:42`, `pairs:3,4`; a table without a key is never written to), and a query, a second collection that is only ever run, goes through a read-only transaction with a time limit, a cursor on Postgres and `sql_select_limit` on MySQL, 200 rows at most, answered as JSON lines. MySQL's read-only transaction doesn't stop DDL, so the statement check is what keeps a query to reading; the docs tell people to make a read-only database user as well. Lists take `?search=` (only where the collection has a `searchHint`; Granola has none), `?filter=` (the collection's `filterField`, such as `?filter=Draft`), `?parent=` (only in a `nested` collection: the list inside a record, answered with its `trail`, the records above it; a record made there goes in it) and `?page=` (`list-query.ts`) and answer a page, newest first (a mailbox's 50 emails, Granola's 30 days), with the next page's token; a mailbox's token holds where each folder goes on, so paging through the merged list shows every email once, and its search uses Gmail's own syntax on Gmail (`X-GM-EXT-1`) and IMAP text search elsewhere.

MCP clients sign in with OAuth 2.1 (`src/oauth/`), Personal Agent Proxy being its own authorization server: metadata under `/.well-known/`, Dynamic Client Registration at `/oauth/register` (open to anyone, each registration first deleting the clients that registered over a day ago and never finished a sign-in), `/oauth/authorize` sealing the request into the web app's `/connect-agent` page, where the person chooses the agent login the client works as or makes one, and `/oauth/token` with PKCE (S256 only) and refresh tokens replaced on every use; codes and tokens are kept as their SHA-256, and revoking an agent ends its clients' tokens. These endpoints take any origin (CORS), since none reads a cookie; credentials and Information records are stored encrypted with `ENCRYPTION_KEY` (`src/utils/secret-crypto.ts`). Has its own `.prettierrc.json` with a 200-column print width - `skills/` - Agent skills, symlinked into `.claude/skills` and `.codex/skills` by `bun run setup` ## The app Personal Agent Proxy holds the integrations and personal information an AI agent needs, so every agent company does not have to rebuild them and you do not have to trust each one's security. A human connects services and hands out agent logins; an agent signs in with one and works through what it was given. Everything is served by `packages/api`; the web app has no data of its own. -- **Model**: an integration from the catalog (`@proxy/integrations`: Email over IMAP and SMTP, Granola's meeting notes, Notion's pages and Linear's issues over their MCP servers) has the actions an agent can be allowed with a connection of it (Read, Archive, Write drafts, Send) and collections, each a list of fields with the actions reading and writing it need, and the commands it offers beyond editing (Mark as read, Archive, Send), each needing one action. A command runs on a `record`, where its `where` picks out which (Archive only in the inbox, Send only on a draft), or on values typed in (`new`: sending a new email). A mailbox is one collection, its folder a field the agent side filters by. A `nested` collection is a tree, as Notion's pages are: a record can hold others of the collection (`hasChildren`), listed inside it with the list tool's `parent` and made inside it with the create tool's, and access is the same anywhere in it. Integrations join the catalog once they work end to end; Google Workspace comes later. A connection is a connected integration and its account, owned by the organization; an integration can be connected more than once, such as two mailboxes. Information is the built-in `info` connection (addresses, payment cards, notes), made with the organization, so access and the agent side treat it like any other. Nothing is copied from a provider: every request goes to it live. Fields marked `system` are set by the provider, never typed in. +- **Model**: an integration from the catalog (`@proxy/integrations`: Email over IMAP and SMTP, Granola's meeting notes, Notion's pages and Linear's issues over their MCP servers, PostgreSQL and MySQL over their own protocols) has the actions an agent can be allowed with a connection of it (Read, Archive, Write drafts, Send) and collections, each a list of fields with the actions reading and writing it need, and the commands it offers beyond editing (Mark as read, Archive, Send), each needing one action. A command runs on a `record`, where its `where` picks out which (Archive only in the inbox, Send only on a draft), or on values typed in (`new`: sending a new email).

A `nested` collection is a tree, as Notion's pages are: a record can hold others of the collection (`hasChildren`), listed inside it with the list tool's `parent` and made inside it with the create tool's, and access is the same anywhere in it. A collection without a `read` action is never listed or opened, only run, as a database's queries are, and a `new` command marked `readOnly` counts as a read for MCP clients. Integrations join the catalog once they work end to end; Google Workspace comes later. A connection is a connected integration and its account, owned by the organization; an integration can be connected more than once, such as two mailboxes. Information is the built-in `info` connection (addresses, payment cards, notes), made with the organization, so access and the agent side treat it like any other. Nothing is copied from a provider: every request goes to it live. Fields marked `system` are set by the provider, never typed in. - **Access** is one list of actions per connection, and every action the catalog lists can be set: what Personal Agent Proxy can do with the provider is the limit. Two layers: the connection's default (a `ConnectionDefault` row per action that is on) and an agent's own setting, on or off, where it differs (`AgentGrant`). An agent gets its own setting, else the default as it is now; an action that `requires` another counts only with it (Archive needs Read; Send needs nothing, so an agent can send without reading the mailbox). A collection's `writes` name the action creating, editing and deleting need, and `editable` which records they apply to (drafts). An agent login is for one agent from `AGENT_PROVIDERS`; each organization can have one login per company. It has a generated username and a password that is shown once. Every request on the agent side is an audit entry, allowed or denied, with what a list searched for. -- **Accounts**: a human signs in with Google or a magic link (`src/auth/` in the api). A session is a `Session` row and an httpOnly cookie; the web app's `/api/me` loader on the human side's route redirects to `/login?callbackUrl=…` without one. Every user gets one `Organization` at sign-up, created with the user. `ALLOWED_SIGNUP_EMAILS` limits who can sign up; the login page asks `/auth/methods` whether to offer Google. In development the login page has a Create dev user button; in development, or without `RESEND_KEY`, the api prints magic links instead of emailing them. Cookies are secure when `APP_URL` is HTTPS. A new organization first goes through the welcome flow (`/welcome`, outside the human side's layout; the human side redirects there until `Organization.onboardedAt` is set, which `POST /api/me/onboarded` does when the flow is finished or skipped): step one is `AgentSetup` (`src/components/agent-setup.tsx`, which New agent and setting an agent up again use too): it picks the agent from `AGENT_PROVIDERS` and does what its `connects` says, an `mcp` agent (Claude, Claude Code, Claude Desktop, Hermes Agent, ChatGPT, Poke) shown the server address and that agent's steps (Claude Code and Hermes Agent use terminal commands) while the page polls for the login its sign-in makes, and over http, as in development, only a `local` agent (Claude Code, Claude Desktop, Hermes Agent) can be picked, the rest greyed out with a pointer to self-hosting on a server with a domain, a `login` agent given a login at once, as a message to paste to it with the sign-in page, username and password, or, for a `vault` agent (Instinct), which won't take a password in chat, as three steps: a message asking it for a link to its vault, the login to fill in on the page it sends, and a message telling it to sign in; step two (`/welcome/connections`) is the catalog, a plus per integration with how many accounts are connected: a mailbox goes to `/welcome/connections/email`, the form on a page with Continue once signed in, and a sign-in started with `?returnTo=welcome` comes back to `/welcome/connections/:id`, the new connection's permissions (its defaults, saved as they are ticked) with Confirm back to the catalog.

A session is a `Session` row and an httpOnly cookie; the web app's `/api/me` loader on the human side's route redirects to `/login?callbackUrl=…` without one. Every user gets one `Organization` at sign-up, created with the user. `ALLOWED_SIGNUP_EMAILS` limits who can sign up; the login page asks `/auth/methods` whether to offer Google.

The agent page shows the server's address and the MCP clients working as the login, each with a Disconnect; the activity log marks requests that came in over MCP (`AuditEntry.via`). -- **Agent side** behind `/agent/login`, with its own cookie: `/agent` lists what the login can do with each connection and the lists it can open, `/agent/:connection/:collection` a collection's records (newest first, 50 to a page with an Older link, narrowed by its `filterField`, such as the folder, in the address as the list tool takes it, `?folder=Draft`, and searched where the collection has a `searchHint`, which says what the search takes; in a nested collection `?parent=` opens it inside a record, with the records above it as breadcrumbs, a record holding others opening into them, and New making one there), `…/new` and `…/:record` the generic `RecordForm` and `RecordFields`, with a button per command the agent may run on the record, and Send beside Save as draft on a new email (loaders in `src/agent-loaders.ts`). Every page runs a tool (`toolName` in `@proxy/integrations`) through the api. It is built for a model driving a browser: no sidebar, no icon-only buttons, nothing that only shows on hover.

A self-signed one needs `NODE_TLS_REJECT_UNAUTHORIZED=0` on the api, never in production. The server's hostname needs a dot and can't be an IP address: `localhost4.localdomain4` reaches 127.0.0.1 on most Linux machines. ## Code Style diff --git a/packages/api/src/connections/mysql/route.ts b/packages/api/src/connections/mysql/route.ts new file mode 100644 index 00000000..054a48f2 --- /dev/null +++ b/packages/api/src/connections/mysql/route.ts @@ -0,0 +1,4 @@ +import {sqlConnectRoutes} from '../sql/route'; + +/** Connecting a MySQL or MariaDB database: Test connection, and Connect. */ +export const {handleTest: handleTestMysqlRoute, handleConnect: handleConnectMysqlRoute} = sqlConnectRoutes('mysql'); diff --git a/packages/api/src/connections/notion/notion-properties.test.ts b/packages/api/src/connections/notion/notion-properties.test.ts index edae3f6a..3a1f2349 100644 --- a/packages/api/src/connections/notion/notion-properties.test.ts +++ b/packages/api/src/connections/notion/notion-properties.test.ts @@ -1,6 +1,6 @@ import {describe, expect, test} from 'bun:test'; -import {notionValues, propertyLines, readPropertyLines, shapeOfType, shapeOfValue} from './notion-properties'; +import {notionValues, propertyLines, shapeOfType, shapeOfValue} from './notion-properties'; describe('propertyLines', () => { test("writes each property on a line, lists joined, leaving out empty ones and what Notion doesn't resolve", () => { @@ -9,24 +9,6 @@ describe('propertyLines', () => { }); }); -describe('readPropertyLines', () => { - const names = ['Status', 'Status Details', 'Notes']; - - test('reads a value by the property it starts with, running on over the lines after it', () => { - expect(readPropertyLines('Status: Contacted\nStatus Details: Sent on Monday\nNotes: first line\nsecond line: still notes\n', names).unwrap()).toEqual({ - Status: 'Contacted', - 'Status Details': 'Sent on Monday', - Notes: 'first line\nsecond line: still notes\n', - }); - expect(readPropertyLines('Status:', names).unwrap()).toEqual({Status: ''}); - expect(readPropertyLines('', names).unwrap()).toEqual({}); - }); - - test('turns down a first line that is no property', () => { - expect(readPropertyLines('Owner: Sam', names).unwrapErr()).toMatchObject({kind: 'validation_error'}); - }); -}); - describe('notionValues', () => { test("writes a value the way Notion's page tools take it, and clears an empty one", () => { expect(notionValues('Status', 'text', ' Contacted ').unwrap()).toEqual({Status: 'Contacted'}); diff --git a/packages/api/src/connections/notion/notion-properties.ts b/packages/api/src/connections/notion/notion-properties.ts index 0f1e32c6..2ae6af0e 100644 --- a/packages/api/src/connections/notion/notion-properties.ts +++ b/packages/api/src/connections/notion/notion-properties.ts @@ -5,10 +5,10 @@ import {ApiErr, type ApiError} from '@proxy/utils'; import {propertyText, type NotionProperties} from './notion-mcp'; /** - * A database row's properties as an agent reads and writes them: one "Name: value" a line, a value - * running on over the lines after it until the next property's name.
