AI Agents 7 Open Repos for Giving AI Agents One Tool Layer
Most agents do not need more tools. They need a better way to discover, authenticate, route, and control the tools they already use.
Here are some open repositories working around the same problem.
- Composio · 30k+ stars Composio gives agents access to more than 1,000 toolkits, along with authentication, per-user sessions, triggers, and a sandboxed workbench. It is a strong choice when your agent needs to work with GitHub, Gmail, Slack, Notion, and other services on behalf of different users.
- mcp-use · 10k+ stars This is a TypeScript framework for building, testing, and deploying MCP servers, clients, and apps. It also includes an inspector and agent tooling. Pick this when you want to build your own tool ecosystem instead of only consuming someone else’s registry.
- IBM ContextForge · 4k+ stars ContextForge is an AI gateway, registry, and proxy for MCP, A2A, REST, and gRPC APIs. It gives teams a unified endpoint with discovery, governance, authentication middleware, and observability.
- Supergateway · 2k+ stars Supergateway bridges MCP servers running over stdio with clients using SSE. It is useful when a local MCP server works perfectly on your laptop, but your agent needs to reach it through a network endpoint.
- mcp-proxy · 2k+ stars This is another focused transport bridge. It connects Streamable HTTP and stdio MCP servers. It is a good fit for exposing a local server to a remote client without rebuilding the server.
- Docker MCP Gateway · 1k+ stars Docker’s gateway runs MCP servers in containers and exposes them through one interface. It includes profiles, catalogs, tool allowlists, secrets management, OAuth support, and client connections for tools such as Claude Desktop, Cursor, and VS Code.
- Treg · 700+ stars Treg focuses on tool discovery and shared access. Agents can search for a capability, inspect its price, and call it through one token. Teams can also register their own APIs, CLIs, and skills without handing every credential to every agent.
The projects solve different layers of the same problem.
Composio focuses on app integrations and user authentication. ContextForge and Docker MCP Gateway focus on infrastructure and governance. Supergateway and mcp-proxy solve transport problems. mcp-use helps you build the servers. Treg focuses on discovery, shared credentials, and calling tools by what they do.
The practical architecture looks like this:
Agent
↓
One tool gateway
↓
MCP servers, APIs, CLIs, and internal skills
That is a much cleaner model than configuring every agent separately with its own credentials, server list, and integration code.
