What is yet-another-MCP-server AGENTS.md?

Repository instructions for YAMS, a Python server that is planned to provide coding-agent tools through MCP, a standard way for applications to offer tools to AI assistants. They document the project layout, development commands, and planned features.

Use them when working on YAMS: install it with uv, run the server, lint and format Python code with Ruff, run tests with pytest, and understand where the server, tools, transport, and configuration code belong.

They give an agent the project’s current conventions and commands, reducing guesswork when installing dependencies, checking code, formatting files, or running tests. The implementation is still minimal, so some documented tools are only planned.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00424	$0.00424
Opus 5.5	$0.00170	$0.00170
Sonnet 5.5	$0.00085	$0.00085
Haiku 4.5	$0.00042	$0.00042

Security

Grade A, and why

yet-another-MCP-server 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.

Project Overview

YAMS (Yet Another MCP Server) - a Python MCP server providing common coding agent tools.

Current state: Early stage. README describes the vision; implementation is minimal.

Toolchain

Package manager: uv
Formatter/Linter: ruff
Testing: pytest (dependencies not yet installed)

Developer Commands

# Install dependencies
uv sync

# Run the server
uv run yams

# Lint
uv run ruff check

# Format
uv run ruff format

# Tests
uv run pytest

Architecture (Planned)

src/yams/
├── server.py      # MCP server entrypoint
├── tools/         # Built-in tools (search, fetch, shell, git, etc.)
├── transport/     # MCP transport layer
└── config/        # Configuration handling

Planned Tools

search - Web search
fetch - Fetch and parse web pages
shell - Execute shell commands
read_file / write_file - File operations
grep - Search project contents
git_status / git_diff / git_commit - Git integration
list_dir - List directories

Key Conventions

Local-first: Tools should work without cloud infrastructure
Unix-style: Small, composable tools
Predictable over magical: Reliable tooling over AI abstractions
Boring technology: Python, JSON, stdio, HTTP

Skills

git-commit

This repo includes a git-commit skill for creating conventional commits.

To use it:

Stage your changes: git add <files>
Run: git commit (the skill will auto-detect type/scope and commit)

Non-Goals

Not an agent framework, orchestration platform, workflow engine, hosted service, or IDE replacement. Just an MCP server.

Changes

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.
