Swagger MCP Adapter
A TypeScript-based MCP server that integrates with Swagger/OpenAPI specifications to expose API endpoints as tools for Large Language Models (LLMs), enabling natural language interaction with any OpenAPI-compliant API.

The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.

No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
4/4 tools missing one or more hints — list_services (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_service_information (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_all_service_information (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +1 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Tool test coverage
Only 0/4 tools referenced in tests (0%)
Write tests that reference each tool by name so every tool has at least one test.
Shell command execution
2 child_process/subprocess calls in production code — runs shell commands (test-mcp-server.js:13, dev-server.js:9)
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Production dependencies are patched
0 critical, 15 high severity in production deps — @modelcontextprotocol/sdk@1.17.4 (high), @modelcontextprotocol/sdk@1.17.4 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Dev dependencies
1 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
Dependency freshness
1/7 production deps stale: swagger-parser@2023-03-04 (3.5y)
