feat(mcp): add humanReadableDescription to MCP tools - #11016
Merged
Conversation
### Description Add `humanReadableDescription` to all MCP tools to provide concise 1-sentence summaries for human consumption, and use this field in `--generate-tool-list` output and documentation tables rather than the longer AI-oriented `description`. ### Scenarios Tested - Unit tests verify `humanReadableDescription` is attached to `ServerTool['mcp']`. - Unit tests verify `markdownDocsOfTools()` formats the table with `humanReadableDescription` and falls back to `description` when not present. - Ran fast test suite (`npm run mocha:fast`) and lint check (`npm run lint:changed-files`). ### Sample Commands ```bash firebase mcp --generate-tool-list ```

Code Review
This pull request introduces a new humanReadableDescription field to MCP tools, allowing for shorter, human-friendly descriptions in user-facing documentation like the README. It updates various tool definitions, updates the documentation generation logic to prioritize this new field, and adds corresponding unit tests. The feedback highlights that several Firestore tools were missed and should also be updated with humanReadableDescription. Additionally, it is recommended to remove redundant optional chaining on tool.mcp in the documentation generator for better consistency.
