agent-bridge

agent-bridge is an MCP server for Claude Code from southlab-ai/Claude-Plugin-Marketplace. Its token cost is not measured, scanned A, original, MIT.

A configured MCP server, a program that gives an agent access to additional tools, called agent-bridge. The input only describes how it starts and the permissions and time limits assigned to it.

In plain words
What is it for?
Use it when the agent needs to connect to the configured agent-bridge server; its concrete jobs cannot be determined from this description alone.
Why use it?
It provides a defined bridge for agent tools, but the input does not say what specific tasks or tools the server supports.

MCP server for Claude Code

Written for Claude Code: $CLAUDE_PLUGIN_ROOT variable. Also seen: mentions Codex; listed in a Claude config.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

Security

Grade A, and why

agent-bridge 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.

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.
