Add read-only GA4 Data API v1 tools: ga_run_report, ga_get_realtime,
ga_get_top_pages, and ga_get_traffic_sources. Includes credential spec,
unit tests, and README.
* feat(arxiv): implement search_papers and initial download_paper tools
* feat(arxiv): improve PDF download handling with temp files and validation (WIP)
Switch to NamedTemporaryFile for safer temp file handling
Force export.arxiv.org domain for PDF downloads
Add custom User-Agent header
Validate Content-Type to ensure PDF response
Improve error handling and cleanup logic
Add timeout to requests
Work in progress – download_paper still under refinement.
* feat(arxiv): replace NamedTemporaryFile with module-level TemporaryDirectory
Switch from NamedTemporaryFile(delete=False) to a shared _TEMP_DIR for
the lifetime of the server process. Scopes file lifetime to the session,
guarantees cleanup via atexit, and removes the need for manual file
handle management.
Expand README with full args/returns/error reference and implementation
notes explaining the temp storage design decision.
* test(arxiv): add comprehensive tests for search_papers and download_paper
fix(arxiv): return structured error instead of raising on invalid PDF content type
- Add full test coverage for search_papers (validation, success, id_list, errors)
- Add full test coverage for download_paper (success, network errors, invalid content, cleanup)
- Mock arxiv client and requests to isolate behavior
- Ensure partial files are cleaned up on failure
- Align download_paper behavior with tool contract (no exceptions, structured responses)
* style(tools): apply ruff formatting to arxiv tool and update lockfile
* feat(tools): add Excel tool for reading/writing .xlsx/.xlsm files
Add excel_tool module with 7 MCP tools:
- excel_read: Read data from Excel files with pagination
- excel_write: Create new Excel files
- excel_append: Append rows to existing Excel files
- excel_info: Get file metadata (sheets, columns, rows)
- excel_sheet_list: List sheet names in a file
- excel_sql: Query Excel with SQL (DuckDB), multi-sheet support
- excel_search: Search values across sheets with match options
Includes 56 tests, openpyxl optional dependency, and documentation.
Fixes#2675
* fix(tools): address excel review feedback and stabilize tests
