No MCP server, no agent surface. - url: https://registry.npmjs.org/-/v1/search?text=stannp status: 200 note: >- No @stannp/* or *-mcp package. `@pipedream/stannp` is a Pipedream platform connector, not an MCP server. note: >- CANDIDATE ONLY. Stannp publishes no MCP server, hosted or local. The tools below are derived one-per-operationId from the OpenAPI already in this repo so an implementer has a starting shape; each tool's real input contract is that operation's parameters/requestBody in the referenced spec. Auth would be the API key Stannp already uses (HTTP Basic with the key as username, or an `api_key` query parameter). Nothing here is an endpoint an agent can call today. server: name: stannp transport: null url: null tools: - name: get_account_balance description: Retrieve the current Stannp account balance. source_operation: openapi/stannp-account-api-openapi.yml#getAccountBalance -
