Install & configure

Prerequisites

required
Download agent-tool binary
Download the prebuilt binary for your OS from Releases
https://github.com/knewstimek/agent-tool/releases/latest

Install in your client

Paste into the AI you're chatting with — it will figure out the rest

Please install the `agent-tool` MCP server into my current AI client (that's you).

Required prerequisites (do these first if not already done):
- **Download agent-tool binary** — Download the prebuilt binary for your OS from Releases (https://github.com/knewstimek/agent-tool/releases/latest)

Canonical MCP server config (stdio transport):
- command: `agent-tool`
- args: []
- optional environment variables:
  - `AGENT_TOOL_FALLBACK_ENCODING`: Fallback file encoding when auto-detection fails (example: `UTF-8`)

Note: Can also run `agent-tool install` to auto-register with detected agents.

Add this MCP server to my current client's config in the correct format for you. If you need secrets or credentials I haven't provided, ASK me — do not invent values or leave raw placeholders. After adding it, tell me how to verify the server is connected.

Note: Can also run `agent-tool install` to auto-register with detected agents.
