blekline-proxy

blekline-proxy is an MCP server for Claude Code, Codex, Cursor from Blekline/blekline-oss. Its token cost is not measured, scanned A, original, AGPL-3.0.

A local router for Model Context Protocol (MCP) tool calls. It checks each call against Blekline rules that can mask or block it, then forwards approved calls to another MCP server.

In plain words
What is it for?
It is for controlling tool access to services such as Daytona, Modal, E2B, Cloudflare, Vercel Sandbox, or a mock server.
Why use it?
It adds a review step before connected tools receive requests, helping prevent calls or data that violate the configured rules from being forwarded.

Security

Grade A, and why

blekline-proxy 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 3d 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.
