openrouter-fusion is an MCP server for Claude Code from tboome33/openrouter-fusion-mcp. Its token cost is not measured, scanned A, original, MIT.

A local MCP server that asks several AI models to consider a question and combines their work through a judging model. MCP is a standard way for an AI agent to use external tools.

What is it for?
It supports asynchronous multi-model deliberation for high-stakes answers through OpenRouter Fusion and requires six environment variables to run.
Why use it?
It provides multiple model opinions for answers where one model may be insufficient, with named quality, budget, or custom configurations.

Security

Grade A, and why

openrouter-fusion 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 11d 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.

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.
