"FIRST" matching MCP servers:

Replay-verified minimal JSON reproductions and deterministic TypeScript/OpenAPI drift checks. Local-first CLI and MCP server.

A lightweight, local-first MCP server for executing HTTP requests and managing API collections and environments without cloud dependencies. It enables testing APIs, handling authentication, and importing OpenAPI specifications directly within MCP-compatible workflows.

Enables AI agents to connect to Charles Proxy for live and historical traffic analysis, summary-first insights, request detail inspection, and data-driven mock creation via Map Local/Remote.

A keyboard-first API client that stores requests and environments as plain files, and exposes its workspace over MCP so agents can browse, send, and create requests with vault access.

Converts existing HTTP operations and cURL commands into structured, local-first MCP tools that AI agents can call safely.

Kāhea is a local-first MCP server that enables coding agents to inspect API descriptions, plan exact requests, grant precise capabilities, and invoke operations with sealed evidence.

Exposes selected operations of an existing REST/OpenAPI app as MCP tools with generated schemas, permission annotations, and a risk class, requiring explicit opt-in before anything is listed and a second flag for destructive calls. Enforces security-first guardrails such as environment-injected auth, a single confined base URL, timeouts, response caps, rate limiting, and a local test console for trying tools.
