Best for
  • Teams shipping multi-tenant agentic products
  • Developers who want managed OAuth
  • Framework users needing broad tool coverage
  • Python developers building MCP servers
  • Teams wrapping internal services as tools
  • Prototyping MCP clients
Pros
  • Handles OAuth and per-user token storage so you don't have to
  • Large catalog of prebuilt app connectors
  • Exposes tools over MCP and native framework SDKs
  • Strong multi-tenant/auth story for production apps
  • Observability and logging for tool calls
  • Minimal-boilerplate, decorator-based API
  • Auto-generates schema, validation, and docs
  • Powers a large share of MCP servers
  • Open source and free
  • Handles transport, auth, and lifecycle
Cons
  • 2026 usage-based pricing can escalate sharply at production volume
  • Free tier is hard-capped and mainly for development
  • Hosted-only core; limited self-hosting
  • Vendor lock-in around the managed auth layer
  • Connector quality and coverage vary by app
  • Python only
  • Fast-moving API across 1.0/2.0/3.0 requires version pinning
  • Hosted FastMCP Cloud/Horizon are separate paid products
  • Relationship between the SDK-bundled version and standalone project can confuse newcomers
  • Production hardening still on the developer
