Connect Pollaris to Cursor

Cursor reads MCP servers from .cursor/mcp.json for one project or ~/.cursor/mcp.json for your user account. Pollaris uses a remote Streamable HTTP endpoint with a Bearer token. Cursor's current MCP format is documented in the official Cursor MCP guide.

Configure a personal connection

Create or edit ~/.cursor/mcp.json:

{
  "mcpServers": {
    "pollaris": {
      "url": "https://mcp.pollaris.cc/mcp",
      "headers": {
        "Authorization": "Bearer plr_mcp_v1_REPLACE_ME"
      }
    }
  }
}

Use a personal config for a literal secret. Do not commit this file.

For a project-shared configuration, create .cursor/mcp.json but do not put a real key in version control. Whether environment placeholders are supported can depend on the Cursor surface/version; verify the resolved connection before relying on one. A user-level file is the safest portable choice for the credential.

Enable and test it

1. Open Cursor settings and go to Tools & MCP.
2. Reload the MCP servers, or restart Cursor.
3. Confirm pollaris is enabled and its tools appear.
4. In Agent chat, ask: Use Pollaris to list my accessible workspaces.
5. For a write-key test, ask the agent to create a small draft, review the tool call, and confirm the returned editor_url opens the draft.

Cursor Agent uses MCP tools when relevant. You can explicitly say Use the Pollaris MCP tools if it answers without calling them.

Remove or replace the key

Delete the pollaris entry to remove the connection. When rotating a key, replace only the token value, save the file, then reload the MCP server.

Troubleshooting

• Unauthorized: The key is incomplete, expired, revoked, or copied with extra spaces.
• Server not found: Confirm the JSON is valid and the file is exactly .cursor/mcp.json or ~/.cursor/mcp.json.
• No tools: Confirm the URL ends in /mcp, then restart Cursor.
• Workspace missing: The key was not granted that workspace, or your Pollaris membership changed.
• Write call denied: The key needs pollaris.forms.write, and you must be an editor or owner in that workspace.
