prerenderbuddy

prerenderbuddy is an MCP server for Claude Code from kopachlager/prerenderbuddy-plugins. Its token cost is not measured, scanned A, original, Apache-2.0.

A local MCP server that provides Prerender Buddy tools for checking public websites and, when configured, workspace evidence. MCP is a way for an agent to call tools from another program.

In plain words
What is it for?
Use it to run public crawler diagnostics or inspect optional Prerender Buddy workspace information when an API key is configured.
Why use it?
It gives the agent a defined local connection for crawler diagnostics without requiring those checks to be built into the coding project.

Security

Grade A, and why

prerenderbuddy 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 1mo 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.
