MCP server for discovering and calling 400+ practical APIs through six compact tools, with free catalog search and pay-per-call x402 execution on Base.

Turn any OpenAPI 3.x spec into a runnable, stateful API environment for AI agents. Test real integration flows — multi-step workflows, persistent state, webhook delivery, retries, and edge cases — instead of guessing from docs or mocking endpoints. Generate committable markdown reports directly from Claude/Cursor. Includes 50+ pre-validated APIs like Stripe, GitHub, Twilio, OpenAI, and more.

Parses Swagger 2.0 and OpenAPI 3.x specifications, exposing API endpoints, schemas, and authentication through MCP tools with local caching to reduce token usage.

Turn any OpenAPI spec into MCP tools for Claude — instantly. Point mcp-openapi at any OpenAPI 3.x spec and Claude can call every endpoint through natural language. No custom integration code. No manual tool definitions. One line of config.

MCP server for API test case generation from Swagger/OpenAPI specs. Parses Swagger 2.0 and OpenAPI 3.x, generates test cases across 8 categories (positive, negative, boundary, auth, security, idempotency, pagination, business logic), and exports to Postman, TestRail, Allure, k6, pytest, Gherkin, and CSV. Supports internal corporate APIs with auth headers. Auto-saves export files to your working di

Enables AI assistants to manage Xano databases through the Model Context Protocol, allowing users to create, modify, and delete tables, edit schemas, and extract API documentation.

Integrates XAPIHub API services with the Cursor IDE to enable user authentication, real-time data fetching, and connection diagnostics. It allows developers to interact with their XAPIHub organization and manage user details directly through natural language commands.

Enables Claude Code to interact with any GraphQL API by introspecting the schema and exposing queries and mutations as individual callable tools.

Enables AI agents to discover and read Typeship API documentation and execute API operations through schema-validated MCP tools, with optional read-only mode and configurable result limits.

Provides AI assistants with access to OpenAPI specifications, enabling API discovery, schema retrieval, and direct API execution with support for OAuth 2.0 and other authentication methods.

Exposes Bruno CLI as tools for AI agents, allowing them to discover, inspect, and execute Bruno API collections through the MCP protocol.

Enables MCP clients to invoke every typeship API operation as a tool, with spec-derived input schemas, argument validation, read-only mode, and selective tool exposure.

Compiles OpenAPI 3.x documents and HTTP manifests into verified MCP tools, serving only operator-approved HTTP operations over Model Context Protocol stdio.

Point it at an OpenAPI 3.x document and get an MCP server that exposes the API's endpoints as typed, validated tools for Claude or any MCP client.

Enables interaction with Qonto's Business API for banking operations. Supports all API key-accessible endpoints for managing business banking transactions and account information.

HTTP-4-MCP configuration tool allows you to easily convert HTTP API into MCP tool, writing the code written. Through simple interface operation, you can quickly configure an mcp-server.

Runtime MCP server that dynamically bridges any OpenAPI 3.x spec to MCP tools.

Serves any OpenAPI 3.x/Swagger 2.x API as a local MCP server over stdio, converting every operation into a tool that proxies requests to the upstream API with configurable headers and fixed parameters.

Enables LLMs to explore and query OpenAPI specifications, allowing natural language interaction with API endpoints, parameters, request bodies, and response schemas from any OpenAPI 3.x spec.

Dynamically converts any Swagger 2.0 or OpenAPI 3.x specification into callable MCP tools, enabling AI clients to interact with API endpoints.
