Configure Sentry MCP server for pi (project-scoped)

segment 1 of 3

Explore Sentry MCP setup and create initial config file for Cursor

Abandoned

The user asked about setting up the Sentry MCP server. The assistant checked existing Sentry configuration, researched the Sentry MCP setup, and created a .cursor/mcp.json file with the HTTP URL endpoint. However, the user later clarified they use pi, not Cursor, making this config file incorrect and leading to its deletion.

outcome

Created .cursor/mcp.json with the hosted Sentry MCP endpoint, which was later abandoned because the user does not use Cursor.

next steps

—

key decisions

  • Create .cursor/mcp.json as the initial approach (later undone).

segment 2 of 3

Determine correct MCP configuration location for pi and move config

Done

After the user clarified they use pi (not Cursor), the assistant investigated pi's MCP configuration discovery mechanism, found that project-scoped config belongs in mcp.json at the repo root (loaded by @spences10/pi-mcp), deleted the .cursor/mcp.json and empty .cursor directory, and created mcp.json at the project root with the same Sentry MCP config.

outcome

mcp.json created at the repo root with the Sentry MCP server configuration; .cursor/mcp.json deleted.

next steps

  • Restart pi session and run /mcp connect sentry to connect the Sentry MCP server.

key decisions

  • Place project-scoped MCP config in mcp.json at the repo root for pi, not in .cursor/.

segment 3 of 3

Resolve 401 authentication error for Sentry MCP connection

Abandoned

When trying to connect the Sentry MCP server in pi, a 401 invalid_token error occurred. The assistant identified that the HTTP URL (https://mcp.sentry.dev/mcp) requires OAuth browser flow which pi's HTTP MCP client cannot complete. The solution was to switch to stdio transport using npx @sentry/mcp-server@latest. The mcp.json was updated accordingly. Two authentication paths were provided: device login via npx @sentry/mcp-server@latest auth login, or creating a Sentry User Auth Token and exporting SENTRY_ACCESS_TOKEN with MY_PI_MCP_ENV_ALLOWLIST.

outcome

mcp.json updated to use stdio transport; two authentication methods documented. The connection is not yet established.

next steps

  • Run npx -y @sentry/mcp-server@latest auth login (or export SENTRY_ACCESS_TOKEN with appropriate scopes)
  • Set MY_PI_MCP_ENV_ALLOWLIST=SENTRY_ACCESS_TOKEN if using token method
  • Restart pi session and run /mcp connect sentry
  • Verify with npx -y @sentry/mcp-server@latest auth status

key decisions

  • Switch from HTTP remote endpoint to stdio transport using npx @sentry/mcp-server@latest.
  • Use device code flow or a user auth token instead of OAuth browser flow.
  • Do not commit the Sentry access token to the repository.

open questions

  • Will the device code flow work when launched from pi's stdio subprocess (may lack TTY)?
  • Does the user have the required permissions to create a Sentry User Auth Token with the necessary scopes?
  • Whether the connection will succeed after authentication.
