v0.1.3

Documentation

• Added OAuth re-authentication instructions to CLAUDE.md (#3)
  • ./gsuite-mcp auth <label> to re-auth expired tokens
  • ./gsuite-mcp accounts to check authenticated accounts

v0.1.2

Bug Fix

All Google Docs write operations now work — previously every docs tool (append, insert, replace, delete, format, tables, images, headers/footers, batch update) failed with "Must specify at least one request" because nil was passed to the Docs API instead of actual request objects.

Fixed tools (15)

• docs_append_text, docs_insert_text, docs_replace_text, docs_delete_text
• docs_format_text, docs_clear_formatting, docs_set_paragraph_style
• docs_create_list, docs_remove_list
• docs_insert_table, docs_insert_link, docs_insert_page_break, docs_insert_image
• docs_create_header, docs_create_footer
• docs_batch_update

Additional improvements

• docs_replace_text returns actual replacement count from API (was hardcoded to 1)
• docs_batch_update parses JSON into typed request objects and returns real reply count

v0.1.1

Fix

• Renamed gmail_get_message → gmail_get as primary tool name, matching the convention of all other services (drive_get, docs_get, contacts_get, sheets_get, tasks_get)
• Added gmail_get_message as backward-compatible alias
• AI agents no longer hallucinate a nonexistent tool name after gmail_search
