Large Language Models (LLM) & AI Market: Live API specs for coding agents
Jonas Gauffin published a technical post describing docs-mcpserver, a tool that fetches an OpenAPI specification from a running service, caches it, and serves API documentation one operation at a time. The approach lets coding agents request only the single path/operation they need (reducing token usage) and keeps a last-known-good cached spec so frontend development can continue even if the backend is offline. The article includes a minimal configuration example, an installation command, and links to the project's GitHub repository and npm package.
A practical developer tool for LLM-based coding agents that reduces token usage and keeps API specs up-to-date; relevant to teams building agent-assisted developer workflows but not industry-shifting.
