MCP Client - 0xcat Akio

What is MCP?

The Model Context Protocol (MCP) is an open standard for connecting AI agents to external tools and data sources. Akio can connect to any MCP-compatible server, giving the LLM access to additional capabilities like browser automation, database queries, or custom APIs.

Listing registered servers

akio mcp list

This shows all registered MCP servers and the tools each one exposes to the model.

Adding a server

akio mcp add --name <NAME> --command <COMMAND> --args <ARGS...>

Flag	Description
`--name`	A unique friendly name for the server
`--command`	The executable used to start the server
`--args`	Arguments passed to the command

Akio spawns the server process when starting a session and communicates over stdin/stdout using the MCP protocol. Example — browser automation via browser-use:

akio mcp add --name 'browser' --command 'uvx' --args --from 'browser-use[cli]' browser-use --mcp

Removing a server

akio mcp remove --name <NAME>

Example:

akio mcp remove --name browser

Example: adding a Node-based MCP server

# Add a server that runs via npx
akio mcp add --name my-server --command npx --args "-y" "my-mcp-package"

# Verify it appears with its tools
akio mcp list

# Start a session — the server's tools are now available to the agent
akio run -m Qwen3-8B-Q4_K_M.gguf

Notes

MCP servers are persisted across sessions — you only need to add once.
Multiple servers can be registered simultaneously; all their tools are merged into the agent’s tool set.
Akio launches each server process fresh at the start of every akio run session.
