"FIRST" matching MCP servers:

A curriculum that teaches AI agents how to spend their own money. Sixteen lessons from "what is a wallet" to your first x402 purchase. Teacher, not butler — never signs, pays, or holds keys.

Enables developers to enforce versioned data contracts for MCP tool schemas, with additive-only evolution checked in CI, SHA-256 pinning against rug pulls, and signed handles instead of protocol sessions.

Enables querying hardcoded weather data for Delhi, Mumbai, and Bangalore through natural language, using a single stdio-transport tool that Claude can discover and call.

Provides an add tool for summing two numbers and a greeting://{name} resource that returns a personalized greeting over stdio.

A simple MCP server that exposes a 'greet' tool which returns a friendly greeting for a given name.

A local MCP server that connects Claude Desktop to execute custom local code, such as generating custom greetings.

A real, runnable MCP server exposing three read-only tools (inventory, pricing, hours) with a CLI agent that lets Claude discover and call them.

Exposes locally-built AI tools to Claude, enabling article summarization, promo generation, and semantic search over an Obsidian vault.

Enables AI clients to browse, read, update, and search a document store through tools, resources, and prompts, including summarizing and comparing documents via URI-addressable resources and reusable prompt templates.

MCP server exposing First CH Tools' free web-tool logic for WCAG contrast, JP character counting, WebP conversion, JSON-LD, and llms.txt generation to AI agents.

An MCP server for controlling Adobe Photoshop from AI assistants, with Windows-first workflow, structured state, smoke-tested action playback, and a bundled Codex skill for image editing.

Enables privacy-preserving document retrieval by exposing read-only search tools over MCP, allowing agents to query local vector and structured indexes without sending data to the cloud.

A simple Model Context Protocol server that provides an addition tool for adding two numbers.

Enables to perform mathematical calculations, retrieve weather information, and manage files through a standardized MCP interface, showcasing best practices for building MCP servers.

locidx

A local-first, no-API-key MCP server that enables LLMs to search the web, fetch pages, and read documents using multiple engines and smart fallbacks.

Local-first memory for coding agents. Discovers the memory, instructions, and rules Claude Code, Codex, and Cursor already wrote on your machine, combines them into one canonical Markdown tree, and serves grounded, cited recall through tools like ask_memory and canonical_memory.

MCP server that gives AI chat real vision by reading images, files, logs, and zip archives via local OCR in any language, with privacy-first processing.

Enables local-first, verbatim memory retrieval for AI agents, storing notes and text across sessions and retrieving original passages without generative rewriting.

Embedded memory and retrieval engine for AI agents, providing local-first memory with MCP support for multi-agent access control.
