Provides access to HMR (Hot Module Replacement) documentation for reactive programming and hot reloading in Python through a streamable HTTP protocol endpoint, serving guides, examples, conceptual explanations, architecture overviews, and complete library source code.

A server can change after it's graded. Re-run the automated scan to refresh this report.
This grade is deterministic and reproducible: the same server surface always yields the same grade under a given algorithm version. It is a real automated assessment computed by the MCPGrade engine from what the probe actually observed — not a fabricated or opinion score. It is not a manual human pentest, so it can miss context-specific risks.
Every signal below was measured directly by the automated probe. The grade is derived only from evidence like this — nothing is assumed.
The hmr-docs MCP server exposes 3 tools, focused primarily on general-purpose capabilities. Its published description reads: "Provides access to HMR (Hot Module Replacement) documentation for reactive programming and hot reloading in Python through a streamable HTTP protocol endpoint, serving guides, exa…". It communicates over Streamable HTTP using the 2026-07-28 protocol revision, and does not require authorization to connect. MCPGrade currently rates hmr-docs D — the assessed surface is high-risk and should be remediated before use. Its most notable findings include "Metadata dictates tool-call ordering" and "Cross-tool shadowing". This report is a deterministic, reproducible automated assessment: the same observed surface always yields the same grade under a given algorithm version, and it is refreshed as new scans arrive and free to read — but it is not a substitute for a manual human security review. Always re-check hmr-docs's advertised tools, transport security, and authorization posture before connecting an autonomous agent or sharing sensitive context with it.
Add hmr-docs to an MCP client using the endpoint below. Review the grade and findings above before granting an autonomous agent access.

The text tells the model WHEN to call this tool relative to others ("always call first", "before any other tool", "chain to X tool") — a toxic-flow injection that hijacks the agent’s orchestration rather than describing the tool.
