1. fastmcp

   1 24 27,945 9.9 Python

   🚀 The fast, Pythonic way to build MCP servers and clients.

   

   Project mention: The portal said "Live." For a few hours the page kept saying the connector didn't exist. | dev.to | 2026-09-24

   This has caught other people too. A pull request to FastMCP describes the same problem: its titles were going only into the top-level field, so the Claude connectors directory saw the tools as nameless. If the portal says your tools are missing titles and you can clearly see the titles in the schema, check annotations.title before doing anything more dramatic. That string is also what users see in the confirmation dialog, so they get "Create post" instead of create_post.

5. mcp-context-forge

   4 8 4,557 9.9 Python

   An AI Gateway, registry, and proxy that sits in front of any MCP, A2A, or REST/gRPC APIs, exposing a unified endpoint with centralized discovery, guardrails and management. Optimizes Agent & Tool calling, and supports plugins.

   

   Project mention: Every AI toolchain is inventing its own safety layer. We shipped one that works across all of them. | dev.to | 2026-05-12

   Anthropic shipped Claude Code hooks — PreToolUse, PostToolUse, Notification, and friends. They run as subprocesses, get JSON on stdin, and decide whether the tool call proceeds. OpenAI ships tool guardrails in the Agents SDK — Python (and now TS) callables you attach to a tool, with tripwire booleans that abort the run. The MCP ecosystem is sprouting gateways and proxies for the same purpose: MCPX, IBM ContextForge, Microsoft's MCP Gateway, Lasso Security's MCP Gateway — all reasonable answers to the same wire-level question.

15. arcade-mcp

    13 1 889 - Python

    MCP Server Framework and Tool Development library for building custom capabilities into agents.

    

    Project mention: Should you build or buy an MCP runtime for enterprise AI agents in 2026? | dev.to | 2026-05-13

    Agent-optimized tools. Arcade's catalog of over 8,000 agent-optimized MCP tools are not API wrappers. They translate natural-language intent into structured API calls, so an agent asked to "send this to Finance" does not have to hallucinate the target recipient_user_id. The token cost shows up in benchmarks: for identical CRM queries, intent-level tooling produced 100x fewer response tokens than a raw API-passthrough approach, with token output equivalent to 3.7% of a 200K context window versus 373%. At scale, that overhead translates to context-window overflow in multi-step workflows and degraded agent accuracy. The runtime handles parallelized tool execution, failover, and retries. The Arcade MCP Framework lets you build custom proprietary tools that federate into the same control plane with the same auth and governance wrapping.

16. mcp-nixos

    14 4 849 8.6 Python

    MCP-NixOS - Model Context Protocol Server for NixOS resources

    

    Project mention: Ask HN: Who is using MCP in production? | news.ycombinator.com | 2026-09-03

    In general the advantage of MCP would be the possibility for a fine grained control over the tools the agent is allowed to use. But unfortunately there is a myriad of nightmarish awful mcp servers around which are worse than direct API access or even a cli integration.

    I wont advertise any commercial mcp I use but to give an example for a well designed and useful mcp server I could name the nixos mcp. Its useful because it bundles all the nix resources to one endpoint which is more efficient than web search and gives you better control over the sources.

    https://github.com/utensils/mcp-nixos

    Another one would be this filesystem mcp which is in my opinion to prefer over direct cli access. Of course this depends also on your general sandbox strategy but if you just use a generic docker image there are still many potentially dangerous binaries available and such an mcp can restrict the models capabilities.

    https://github.com/modelcontextprotocol/servers/tree/main/sr...

    And of course there are many service provider offering their mcp with its own llm / agent behind e.g. most web search provider. In this case you most likely already use an mcp without noticing it.

17. mcp-client-for-ollama

    15 4 826 8.8 Python

19. mcp-client-cli

    17 1 675 4.5 Python

20. python-utcp

    18 7 652 8.6 Python

    Official python implementation of UTCP. UTCP is an open standard that lets AI agents call any API directly, without extra middleware.

    

    Project mention: UTCP: um protocolo alternativo ao MCP para chamada de ferramentas | dev.to | 2025-12-23

25. nextcloud-mcp-server

    23 2 373 10.0 Python

    Nextcloud MCP Server

    

    Project mention: Open-source memory for coding agents, synced over SSH | news.ycombinator.com | 2026-07-15

    I have developed an open-source memory system for agents accessible over MCP, which makes it possible to access it via any coding agent locally (claude-code) or via mobile (Claude AI, Mistral AI, etc).

    The primary storage mechanism is .md files stored as Notes in Nextcloud; however, since Nextcloud supports a rich ecosystem of apps such as documents, rss feeds, calendar, etc, your knowledge base can grow with you. All content can optionally be indexed and available via semantic search - powered by a Qdrant vectordb.
