mcp-openapi-bridge

mcp-openapi-bridge is an MCP server for Claude Code, Codex, Cursor, Gemini CLI, OpenCode from murilojrpereira/mcp-openapi-bridge. Its token cost is not measured, scanned A, original, MIT.

A local bridge that turns an OpenAPI 3.x description—a document listing a web service's REST endpoints—into separate tools for Claude Code.

In plain words
What is it for?
Use it to call an OpenAPI-described REST API from Claude Code, with optional endpoint filtering, custom headers, authentication, transport, and port settings.
Why use it?
It removes the need to hand-build a tool for every endpoint in an existing API. It can discover the endpoints from a local or online specification, but requires configuration such as the API address and access credentials.

Security

Grade A, and why

mcp-openapi-bridge scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
