Goodday‑MCP is a lightweight Model Context Protocol (MCP) server designed to seamlessly integrate with the Goodday project management platform via its API v2. It enables querying of projects, tasks, and users—without altering any data—making it ideal for secure context-aware applications

A Model Context Protocol server that allows AI development tools like Cursor and Claude Desktop to retrieve detailed YAPI interface information by interface ID.

An MCP server for Apidog that enables listing projects, inspecting API trees, creating modules and folders, and adding or updating requests without manual configuration.

Enables remote-only interaction with the mailery.co hosted HTTPS API via CLI, MCP, and SDK, without running a local mail server or accessing a database/provider account.

Provides access to various AI tools through Model Context Protocol, allowing Claude Desktop users to integrate and use Superface capabilities via API.

Turns any OpenAPI 3.0 or 3.1 document (local file or URL) into typed MCP tools served over stdio, so AI assistants can invoke upstream HTTP API endpoints directly. Handles authentication headers, request validation, and bounded responses for clients like Claude Desktop, Cursor, and VS Code.

Enables AI agents and assistants to dynamically add, update, and remove Mock Service Worker network mocks through MCP tools, with a WebSocket bridge that applies handler changes without restarting or reloading the application.

Provides a tool to inspect and execute actions on a scaffolding API through Siren hypermedia links, enabling management of scaffolding resources without endpoint knowledge.

Enables AI agents and MCP clients to dynamically add, update, and remove Mock Service Worker network mocks via MCP tools, including live handler updates without restarting the application source code.

Enables free, read-only checks of AI agents and MCP servers for conformance, published changes, delivery evidence, and verifiable receipts without requiring an account or API key, using public or non-personal data only.

Enables AI assistants to dynamically add, update, and remove Mock Service Worker network mocks through MCP tools without restarting the application. It also supports scaffolding MSW setup and managing browser-connected mocking sessions via a WebSocket bridge.

Gorgon Scout is a Windows web-application and API security scanner (DAST). This connector exposes it as MCP tools, so your AI assistant can record a target you are authorised to test, run the scan, stream findings, and produce a report. Capture needs no proxy or certificate setup, and it intercepts HTTP/1.1, HTTP/2, and HTTP/3 (QUIC). Works with the free Claude Desktop plan.

Exposes a local Lambda fulfillment handler as a Model Context Protocol server over standard input/output, letting MCP clients such as Claude Desktop and Cursor call the API operations described by an OpenAPI specification. It compiles those specs into pruned tool definitions and emulates Bedrock-style invocation envelopes locally, so handlers can be exercised without deploying to AWS.

Enables AI coding assistants to inspect OpenAPI specs, fuzz live REST endpoints with boundary and adversarial vectors, replay failing anomalies deterministically without AI tokens, and scaffold OpenAPI specs from source routes.

Enables AI agents to dynamically add, update, and remove Mock Service Worker network mocks through MCP tools, without restarting the application source code.
