headroom
Compress tool outputs, logs, files, and RAG chunks before they reach the LLM. 20% fewer tokens for coding agents, 60-95% fewer tokens for JSON, same answers. Library, proxy, MCP server.

No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
7/7 tools missing one or more hints — dynamic_tool_616 (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); dynamic_tool_639 (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); dynamic_tool_658 (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +4 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Tool test coverage
3/7 tools referenced in tests (43%)
Write tests that reference each tool by name so every tool has at least one test.
No eval / new Function
2 eval() or new Function() calls — dynamic code execution
Replace eval / Function with explicit parsing or safer alternatives.
Readable source code
2 files are minified or bundled, which is usually build output rather than concealment
Ship unminified, readable source.
Secrets not logged
30 secret values sent to print
Redact or omit secret values from log output.

Add it once and ask Claude, ChatGPT, or any MCP client to grade a server, surface CVEs, check the publisher, and suggest safer alternatives — before you install.
