Lucid

That's it. The MCP server reads the key from your environment and authenticates every request.

Tools

| Tool | What it does | |------|-------------| | lucid_search_docs | Search real-time documentation for any language, framework or library | | lucid_check_package | Check latest versions, changelogs and compatibility | | lucid_verify_fact | Verify technical claims against live sources before stating them as fact | | lucid_fetch_api_ref | Fetch current API references with type signatures and usage examples |

Example calls

lucid_search_docs({ query: "react useEffect cleanup", language: "typescript" })
lucid_check_package({ name: "next", registry: "npm" })
lucid_verify_fact({ claim: "Bun is faster than Node for HTTP servers" })
lucid_fetch_api_ref({ library: "stripe", symbol: "PaymentIntent.create" })

Skills

Skills automatically trigger the right tools based on what the user is asking. No manual invocation needed.

| Skill | Triggers on | Tool used | |-------|------------|-----------| | lucid-docs | Documentation, API reference, "how to use" | lucid_search_docs | | lucid-packages | Install, package, dependency, version | lucid_check_package | | lucid-grounding | Verify, "is this true", accurate, up to date | lucid_verify_fact | | lucid-api | API, endpoint, function signature, types | lucid_fetch_api_ref | | lucid-freshness | Write code, implement, create, build | All tools |

How It Works

User asks a question
        ↓
Skill detects the intent
        ↓
Tool queries Lucid API
        ↓
Lucid returns verified, real-time data
        ↓
Agent responds with grounded information

The agent never falls back to training data for anything Lucid can verify. If the docs say one thing and training data says another, the docs win.
