| Client coverage note | Local stdio runs on your computer. Streamable HTTP connects to a remotely hosted MCP server. | |
| Access and data | ||
| Authentication | Framework authentication is application-defined; FastMCP documents authentication/deployment helpers but does not impose one universal auth model. | Remote MCP accepts CONTEXT7_API_KEY as an HTTP header. The local package accepts --api-key. The CLI can use OAuth to generate an API key; unauthenticated documentation commands may have lower limits. |
| Cost | Open-source framework; external APIs, hosting, models, or databases used by an application may have separate costs. | A free API key and free usage are documented, with higher-rate or team/enterprise offerings potentially requiring a paid plan. Applicable limits should be checked in the current Context7 dashboard. |
| Permissions | Permissions are defined by the server or client application built with FastMCP; the framework itself does not grant external-service privileges. | The MCP surface resolves library identifiers and queries documentation. It does not require repository or filesystem write access for the documented hosted mode. |
| Data handling | Data handled by a FastMCP app depends on the tools/resources/prompts the developer exposes and on the configured transport. | Context7 states that formulated queries are sent to its API while full prompts, source code, and conversation history are not transmitted; its tool descriptions instruct clients to remove secrets, personal data, and proprietary code. |
| Limitations | ||
| Tradeoffs |
|
|
| Risk context | FastMCP is framework infrastructure, so risk depends on the tools, credentials, transport, and downstream systems an application exposes. Current releases support authentication and role, scope, and component-level authorization patterns. Human-in-the-loop approval is an optional capability or provider pattern, not a default guardrail on every destructive tool. | Primary risks are query disclosure, stale or inaccurate indexed documentation, and accidental API-key exposure. Keep queries free of proprietary details and verify consequential advice against first-party library documentation. |
