semaphor

semaphor is an MCP server for Claude Code from semaphor-analytics/agent-plugin. Its token cost is not measured, scanned A, original, MIT.

A remotely hosted MCP server called semaphor. MCP is a standard way for an AI agent to connect to external tools or services, but the description does not say what semaphor provides.

In plain words

What is it for?: The description is too thin to name a concrete job it supports.
Why use it?: The available description does not identify a specific problem it solves or the data it can access.

Written for Claude Code: shipped in a Claude Code plugin. Also seen: listed in a Claude config.

Part of the semaphor plugin — 1 skill, 1 MCP server shipped together

Good fit The description is too thin to name a concrete job it supports.

Security

Grade A, and why

semaphor 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 20d 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.
