unmcp: Instructions file for Codex

AGENTS.md

unmcp AGENTS.md is an instructions file for Codex, OpenCode from Am1n3e/unmcp. It costs 613 tokens per session, scanned A, original, MIT.

A repository-specific instruction file for unmcp, documenting installation, command-line use, architecture, linting, formatting, and type-checking commands.

In plain words
What is it for?
Use it when developing the unmcp command-line tool, which provides direct commands for calling MCP servers. MCP is a standard way for agents to use external tools.
Why use it?
It tells an AI coding agent how this Python project is organised and how changes should be checked before they are accepted.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions AGENTS.md.

This is Am1n3e/unmcp's own configuration. It tells Codex and OpenCode how to work on unmcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything unmcp configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

unmcp AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Architecture Overview

unmcp is a CLI that provides direct command-line access to MCP (Model Context Protocol) servers, bypassing the protocol overhead for simpler workflows.

Two Execution Modes

On-Demand Mode (default): Each tool call spawns a new MCP server process, executes the tool, and exits. Simple but slower for repeated calls.

Persistent Mode: A daemon process keeps the MCP server running, communicating via Unix socket. Tool calls connect to the daemon rather than spawning new processes.

Core Components

  • cli.py - Click-based CLI with DynamicServerGroup that dynamically creates subcommands from cached tool schemas. Server tools appear as unmcp <server> <tool>.

  • services/server_manager.py - ServerManager handles server lifecycle: init (discover tools), start (spawn daemon), stop, status.

  • services/tool_runner.py - ToolRunner executes tools, automatically routing to socket (persistent) or spawning new process (on-demand).

  • daemon.py - DaemonServer maintains MCP session and exposes it via Unix socket. Accepts JSON-RPC style messages (call_tool, list_tools, shutdown).

  • mcp_client.py - MCPClient wraps the MCP SDK's stdio transport for one-shot server connections.

Data Flow

  1. unmcp clt init <server> - connects to MCP server, caches tool schemas to .unmcp/servers/<server>.json
  2. unmcp <server> <tool> - CLI looks up cached schema, builds Click command, invokes ToolRunner.call()
  3. ToolRunner checks for socket at .unmcp/sockets/<server>.sock:
    • If exists: sends request via socket to daemon
    • If not: creates MCPClient, spawns process, calls tool, exits

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
