A locally running companion package for the Model Context Protocol SDK. MCP is a standard way for coding agents to connect to external tools and data.

Use it in local Python-based MCP setups that need the modular-mcp package.

It provides an additional, modular layer around the SDK, with parts kept separate so they can be extended independently.

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.

agentmods

npx agentmods add mcp/lamchantuong/modular-mcp/modular-mcp

Clone the repo

git clone --depth 1 https://github.com/lamchantuong/modular-mcp

Made for: Claude Code, Codex, Cursor, Gemini CLI, OpenCode.

Security

Grade A, and why

modular-mcp 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 5d 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.

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.

modular-mcp is an MCP server published in the GitHub repository lamchantuong/modular-mcp (0 stars, last pushed 12d ago), licensed MIT. Its token cost is not measured: an MCP server costs its tool schemas, not its config file. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
