The honest brief

FastMCP

v2 is the standalone superset most Python MCP servers build on; v1 was folded into the official MCP Python SDK.

  • Decorate a function, get an MCP tool
  • Handles transport, auth, lifecycle
  • Apache-2.0, free to self-host
  • Pythonic, low boilerplate
  • Python-only
  • Managed hosting is a separate paid product
  • MCP spec still evolving

Gram

Curates and composes business-level tools from your OpenAPI or TypeScript instead of exposing raw API endpoints, so agents get cleaner toolsets.

  • Open source (AGPL-3.0)
  • Hosted MCP servers, no infra
  • OpenAPI and TypeScript sources
  • Built-in OAuth 2.1 proxy
  • Tool curation, not raw APIs
  • Still in public beta
  • Usage-based costs at scale
  • Tied to Speakeasy ecosystem
  • Newer, smaller community
