Mu provides 67 internet tools for AI agents via a single MCP endpoint

Unified Tool Access for AI Agents

Mu has launched a system that provides AI agents with access to 67 internet tools, such as news, web search, email, and calendar functions. These tools are consolidated behind a single MCP (Micro Control Protocol) endpoint, simplifying the integration process for agents.

Proprietary Tool Implementation

Unlike platforms that act as wrappers for external APIs, Mu operates its own services for these tools. For example, it runs its own mail server, feed aggregator, and search index. This approach means the tools represent Mu's internal capabilities rather than a catalog of third-party products.

Deployment and Authorization

The platform can be used as a hosted service at micro.mu or self-hosted via a single Go binary. Authorization for the MCP endpoint uses a specific authorization specification, with clients like Claude Desktop and Cursor supporting it. For other clients, Personal Access Tokens can be generated.

Cost and Open Source Model

Accessing Mu's own content is included, while calls that incur costs, such as model calls or paid third-party services, draw from a user's credit balance. Mu is open source, distributed under the AGPL-3.0 license, and each tool is also available as a CLI subcommand.
