dynamic-mcp AGENTS.md

dynamic-mcp AGENTS.md is an instructions file for Codex, OpenCode from asyrjasalo/dynamic-mcp. It costs 780 tokens per session, scanned A, original, MIT.

Project instructions for dynamic-mcp, a Rust proxy server that groups tools from multiple MCP servers and loads their descriptions only when needed. They include the project map, important functions, supported connections, and places to look.

In plain words
What is it for?
Use them when changing or testing dynamic-mcp, including its command-line interface, configuration, proxy server, authentication, transports, imports, and integration tests.
Why use it?
They help an agent navigate an unfamiliar proxy server while keeping its tool descriptions from using unnecessary context.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

dynamic-mcp 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 6d 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.

Overview

MCP proxy server written in Rust that reduces LLM context overhead by grouping tools from multiple upstream MCP servers and loading tool schemas on-demand.

  • Language: Rust 1.75+ (edition 2021)
  • MCP SDK: rmcp v0.12
  • Transports: stdio, HTTP, SSE
  • Distributions: Binary (crates.io) + Python wheel (PyPI via maturin)

What this file has done since we first saw it

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.
