What's New

docs_get_structure tool

Returns document paragraph boundaries with real Google Docs character indices. Each structural element includes type, startIndex, endIndex, named style, and text preview — enabling position-based operations like paragraph shading, targeted hyperlink insertion, and batch formatting.

[
  {"type": "paragraph", "style": "TITLE", "startIndex": 1, "endIndex": 45, "text": "DevX Epic: Three Parallel..."},
  {"type": "table", "startIndex": 300, "endIndex": 800, "rows": 7, "cols": 4},
  {"type": "paragraph", "style": "HEADING_2", "startIndex": 801, "endIndex": 830, "text": "Stream A: Ephemeral..."}
]

Closes #92

What's New

docs_format_by_find tool

Find text in a Google Doc and apply formatting to all matches — no position math needed. Resolves real Google Docs UTF-16 indexes internally, handling tables and structured elements correctly.

{
  "document_id": "...",
  "find_text": "NEXT_PUBLIC_PRACTICE_STATUS",
  "match_all": true,
  "font_family": "Courier New",
  "font_size": 9,
  "background_color": "#e8e8e8"
}

Supports all text formatting options: bold, italic, underline, strikethrough, small_caps, font_family, font_size, foreground_color, background_color, baseline_offset.

Closes #88

What's New

Multi-installation support

--config-dir flag and GSUITE_MCP_CONFIG_DIR env var to run multiple gsuite-mcp instances with different GCP projects. Each installation gets its own client_secret.json, config.json, and credentials/.

Citation tools (11 tools)

Large document indexing with FTS5 search, concept extraction, and citation formatting. Dual-layer storage: Google Sheets (source of truth) + SQLite FTS5 (local cache). Feature-flagged via large_doc_indexing.

• citation_create_index — Create index Sheet in a Drive folder
• citation_add_documents — Chunk and index documents (Docs, Slides, .pptx)
• citation_lookup — FTS5 full-text search across chunks
• citation_get_overview — Index stats, file list, concepts, corpus summary
• citation_get_chunks — Retrieve full chunk content by ID
• citation_verify_claim — Find chunks supporting a claim
