Changes things 1Claude Code: ask
  • learn-hmr-basicsA brief and concise explanation of the `hmr` library.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    A brief and concise explanation of the `hmr` library. This tool provides information on how to use reactive programming or use hot module reloading in Python. As long as the user mentions HMR / Reactive Programming, this tool must be called first! Don't manually view the resource, call this tool instead.

    Annotations the server declares

    • readOnlyHint: true
Only reads 2Claude Code: allow
  • view-hmr-core-sourcesThe full source code (core only) of the HMR library.No findings

    Why it is in this group

    • The name "view-hmr-core-sources" says "view": a word for reading.
    Description, as the server wrote it
    The full source code (core only) of the HMR library. Always call `learn-hmr-concepts` to learn the core concepts before calling this tool. These files are the full source code of the HMR library, which would be very helpful because good code are self-documented. For a brief and concise explanation, please refer to the `hmr-docs://about` MCP resource. Make sure you've read it before calling this tool. To learn how to use HMR for reactive programming, read the unit tests later. The response is identical to the MCP resource with the same name. Only use it once and prefer this tool to that resource if you can choose.

    Annotations the server declares

    • readOnlyHint: true
  • view-hmr-unit-testsThe unit tests (code examples) for HMR.No findings

    Why it is in this group

    • The name "view-hmr-unit-tests" says "view": a word for reading.
    Description, as the server wrote it
    The unit tests (code examples) for HMR. Always call `learn-hmr-basics` and `view-hmr-core-sources` to learn the core functionality before calling this tool. These files are the unit tests for the HMR library, which demonstrate the best practices and common coding patterns of using the library. You should use this tool when you need to write some code using the HMR library (maybe for reactive programming or implementing some integration). The response is identical to the MCP resource with the same name. Only use it once and prefer this tool to that resource if you can choose.

    Annotations the server declares

    • readOnlyHint: true

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Install

Pinned to version 1.0.2. Values in angle brackets are yours to fill in.

claude mcp add --transport http hmr https://pyth-on-line.promplate.dev/hmr/mcp

Claude Code permissions

Allow the reads, ask before a change, deny the deletes. Paste into .claude/settings.json.

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. It assumes the server is installed as hmr. Review it before you use it.
