A Model Context Protocol server configuration that starts a local runtime through Node.js and a bootstrap script shipped with the active Claude plugin. Model Context Protocol, or MCP, is a way for an AI coding tool to use external tools through a standard connection.

Use it when configuring or launching the plugin’s runtime MCP server in Claude Code, especially when checking its command, startup script, or plugin path.

It provides the runtime entry point the plugin needs to start its external-tool service. The configuration uses the active plugin’s installation path instead of relying on a fixed location.

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.

Security

Grade A, and why

runtime 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 yesterday.

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.

runtime is an MCP server published in the GitHub repository PyModel/claude-architect (19 stars, last pushed 3d 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 2026-08-30.
