+# Plaid
+
+Cursor plugin that connects agents to [Plaid](https://plaid.com) through Plaid's official remote [Model Context Protocol](https://modelcontextprotocol.io/) server, the **Dashboard MCP server**.
+
+Debug Items and broken bank connections, review Link conversion data, and check API usage and product metrics for your Plaid integration — the same Production diagnostics and analytics that live in the Plaid Dashboard.
+
+## Install
+
+1. Open **Cursor Settings → Plugins**.
+2. Search for **Plaid**.
+3. Click **Install**, then complete the Plaid Dashboard sign-in prompt.
+
+Or run `/add-plugin plaid` in chat.
+
+## MCP
+
+```json
+{
+  "mcpServers": {
+    "plaid": {
+      "type": "http",
+      "url": "https://api.dashboard.plaid.com/mcp/"
+    }
+  }
+}
+```
+
+The server speaks Streamable HTTP. Plaid also serves a legacy SSE endpoint at `https://api.dashboard.plaid.com/mcp/sse`; this plugin uses the Streamable HTTP URL from Plaid's current docs.
+
+## Auth
+
+Auth is OAuth 2.0 against the Plaid Dashboard. Every request to the server must carry `Authorization: Bearer <access_token>`, and tool calls are scoped to what the signed-in Dashboard user can already see. Plaid documents two ways to get that token:
+
+- **Interactive (MCP clients and hosted assistants).** Add the server URL and sign in to the Plaid Dashboard when prompted. This is the flow this plugin is packaged for.
+- **Machine-to-machine (backend / model-provider APIs).** Call `POST https://production.plaid.com/oauth/token` with `grant_type: client_credentials` and `scope: mcp:dashboard` using your Plaid `client_id` and Production secret, then pass the resulting short-lived access token (15-minute TTL, with refresh token) as the bearer header. This path is for servers, not for the plugin.
+
+> **Note on Cursor OAuth wiring.** This plugin only packages the server definition; it does not bundle an OAuth client ID or secret. Cursor attempts OAuth (including Dynamic Client Registration) when the server returns `401`. If Plaid requires a pre-registered OAuth client for third-party MCP clients, Cursor's static OAuth path (`auth.CLIENT_ID` / `auth.CLIENT_SECRET` on the server entry) or backend wiring will need to be set up separately with credentials issued by Plaid. Do not paste your Plaid API secret into `mcp.json`.
+
+## Before you connect
+
+- You need a Plaid account with **Production** access and at least one product approved for Production. The Dashboard MCP server does not operate on Sandbox data.
+- Data access follows your Dashboard role and team permissions.
+
+## What agents can do
+
+| Category | Capabilities |
+| --- | --- |
+| Items | Diagnose Items and broken bank connections, look up Item status and error details |
+| Link | Review Link conversion data and funnel drop-off |
+| Usage | Check API request volumes, product usage, and usage trends |
+| Teams | List the teams the signed-in user belongs to |
+
+The hosted runtime is the source of truth for tool names and schemas.
+
+## Notes
+
+- The Dashboard MCP server is read-only: it surfaces diagnostics and analytics and cannot move money, create Items, or change your integration.
+- This is Plaid's **Dashboard** MCP server for operating an existing Plaid integration. Plaid separately ships a local, stdio-based Sandbox MCP server (`mcp-server-plaid`) in its AI coding toolkit for building integrations against Sandbox data; that server is not part of this plugin.
+- Plaid may change the tool catalog; check the docs for the current list.
+
+## Docs
+
+- Dashboard MCP server: https://plaid.com/docs/resources/mcp/
+- OAuth token endpoint (`/oauth/token`): https://plaid.com/docs/api/oauth/
+- AI coding toolkit (local Sandbox MCP server): https://github.com/plaid/ai-coding-toolkit
+- Server URL: https://api.dashboard.plaid.com/mcp/

+Logo is Plaid's lattice mark, redrawn as vector geometry and placed on a white tile with padding so it reads well in the Cursor UI.
