| Client coverage note | Local stdio runs on your computer. Streamable HTTP connects to a remotely hosted MCP server. | |
| Access and data | ||
| Authentication | None. | 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 | The ecosystem-official reference package is MIT licensed and has no service fee. Model tokens, local compute, and MCP-host costs remain. | 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 | No external service scopes are required. The local process receives thought text and reasoning metadata from the MCP host and returns structured reasoning state. | 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 | Reasoning text is processed by the local stdio server. The connected MCP host, model provider, and their logs may still transmit or retain tool arguments according to their own policies. Thought logging can be disabled with DISABLE_THOUGHT_LOGGING=true. | 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 | System permissions are low, but prompts and reasoning can contain secrets and repeated calls can increase token cost. Keep sensitive material out of thought text, disable thought logging where appropriate, and use an approved package version. | 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. |
