Google Docs 文档编辑 MCP 服务

google-docs-mcp

Surgical Google Docs editing for AI agents — preserves history, never touches character indices.

An MCP server that makes Google Docs actually usable for LLMs. Standalone — no other tools required beyond a Google Cloud OAuth app.

Compatibility note: the repo, package, CLI, env vars, and default token path now use google-docs-mcp. Backward-compatible google-drive-mcp command and env-var aliases are still accepted so existing setups do not break immediately.

Indexing note: when the MCP reads document content before planning index-based edits, it requests suggestionsViewMode=SUGGESTIONS_INLINE. That keeps returned indices aligned for later documents.batchUpdate calls when the doc contains suggestions. Anchor text is matched against the document as it will read once pending suggestions are accepted (suggested deletions are ignored), so an edit can follow a suggestion made earlier.

Tables note: text inside tables is read by docs_get and can be matched, edited and commented on like any other text.

Non-Docs note: the Docs API treats a Drive file that is not a Google Doc in two ways. A PDF is refused with a bare 400 Request contains an invalid argument, and docs_get then downloads it (up to 20 MB) and returns its extracted text with a read-only warning. A .docx is read without complaint (Docs converts it on the fly) but every write, edits and comments alike, is refused with The document must not be an Office file. Either way the MCP asks Drive what the file is: the edit tools fail with a message naming the file and its type, and the comment tools fall back to Drive comments on the file (see Comments).

Why

The Google Docs API uses character indices for every edit. LLMs are bad at counting characters. Everyone ends up deleting and rewriting entire documents, which destroys version history, comments, and collaborator attribution.

This server uses the same abstraction as code editors: search by text, not by position. You describe what to change; the server finds where it is and handles the index arithmetic.

Quick start

1. Run directly from GitHub

uvx --from git+https://github.com/dbuxton/google-docs-mcp google-docs-mcp --help

That command downloads the package, creates an isolated environment, installs dependencies, and runs the google-docs-mcp entry point.

No PyPI release is required. uvx can execute the tool straight from the GitHub repository.

To pin to a branch, tag, or commit, add a ref to the URL:

uvx --from git+https://github.com/dbuxton/google-docs-mcp@main google-docs-mcp --help

If you prefer a persistent local install instead of uvx, use:

uv tool install --from git+https://github.com/dbuxton/google-docs-mcp google-docs-mcp
uv tool install --from git+https://github.com/dbuxton/google-docs-mcp google-docs-mcp-auth

2. Create a Google Cloud OAuth app

1. Go to console.cloud.google.com
2. Create a project (or select an existing one)
3. Enable these APIs (APIs & Services → Library):
   • Google Docs API
   • Google Drive API
4. Go to APIs & Services → Credentials
5. Click Create Credentials → OAuth 2.0 Client ID
6. Application type: Desktop App
7. Download the JSON file

3. Authenticate

Normal — browser opens automatically:

uvx --from git+https://github.com/dbuxton/google-docs-mcp \
  google-docs-mcp-auth --credentials ~/credentials.json

Or use env vars instead of a credentials file:

export GOOGLE_DOCS_MCP_CLIENT_ID="your-google-client-id"
export GOOGLE_DOCS_MCP_CLIENT_SECRET="your-google-client-secret"

uvx --from git+https://github.com/dbuxton/google-docs-mcp \
  google-docs-mcp-auth

Headless / remote server — no browser on device:

uvx --from git+https://github.com/dbuxton/google-docs-mcp \
  google-docs-mcp-auth --credentials ~/credentials.json --headless
# Prints a URL → open on any device (phone, laptop, etc.)
# Paste the full redirect URL back into the terminal

Already have an auth code:

uvx --from git+https://github.com/dbuxton/google-docs-mcp \
  google-docs-mcp-auth --credentials ~/credentials.json --code "4/0Afr..."

google-docs-mcp-auth resolves OAuth client credentials in this order:

1. --credentials /path/to/credentials.json
2. --client-id and --client-secret
3. GOOGLE_DOCS_MCP_CLIENT_ID and GOOGLE_DOCS_MCP_CLIENT_SECRET

Token is saved to ~/.google-docs-mcp/token.json by default. Override with --out /path/to/token.json.

Tools reference

Document reading

docs_get(doc_id)

Read a Google Doc and return its full structure.

Returns the document title, a list of paragraphs (with text, heading style, and character indices), and the full plain text. Use this first to understand the document before making edits.

docs_get(doc_id="1BxiMVs0XRA5nFMdKvBdBZjgmUUqptlbs74OgVE2upms")

Returns:

{
  "title": "My Document",
  "paragraphs": [
    {"text": "Introduction", "style": "HEADING_1", "start": 1, "end": 14},
    {"text": "This is the body.", "style": "NORMAL_TEXT", "start": 14, "end": 32},
    {"text": "12 months", "style": "NORMAL_TEXT", "start": 36, "end": 46,
     "table_cell": {"table": 0, "row": 0, "column": 1}}
  ],
  "plain_text": "Introduction\nThis is the body.\n12 months"
}

• Tables. Paragraphs inside tables are included in document order; each carries a table_cell with its table, row and column (counted from 0).
• Pending suggestions. The text is the document as it will read once every suggestion is accepted (suggested deletions are hidden). Paragraphs a suggestion touches carry suggestions (IDs) and the result has suggestion_ids and a note. docs_list_suggestions shows what each one changes.

docs_list(query, limit)

List Google Docs from Drive, optionally filtered by a search query. Word files and PDFs are not listed; pass their Drive file IDs to the other tools.

docs_list(query="board deck 2026", limit=5)

Document editing

All editing tools use text anchors, never character indices. The server finds the text and handles the indices internally. Text inside tables is found like any other text.

Every editing tool also takes suggest (default false). With suggest=true the change is recorded as a suggestion for someone to accept or reject, instead of editing the text. See Suggestions.

docs_search_replace(doc_id, find, replace, occurrence, regex, suggest)

Find text in a document and replace a specific occurrence.

# Replace first occurrence
docs_search_replace(doc_id="...", find="Q1 2024", replace="Q2 2024")

# Replace all occurrences
docs_search_replace(doc_id="...", find="ACME Corp", replace="Initech", occurrence=0)

# Regex replace
docs_search_replace(doc_id="...", find=r"\bDraft\b", replace="Final", regex=true)

docs_insert_after(doc_id, anchor, text)

Insert a new paragraph immediately after the paragraph containing anchor.

docs_insert_after(
  doc_id="...",
  anchor="Executive Summary",
  text="Updated as of March 2026 following board review."
)

docs_insert_before(doc_id, anchor, text)

Insert a new paragraph immediately before the paragraph containing anchor.

docs_insert_before(
  doc_id="...",
  anchor="Appendix A",
  text="See the following appendix for supporting data."
)

docs_delete_paragraph(doc_id, anchor, suggest)

Delete all paragraphs containing anchor text (case-insensitive), including ones in tables. Docs won't delete the closing newline of the last paragraph of the document or of a table cell, or of one directly before a table or section break; those paragraphs are emptied rather than removed.

docs_delete_paragraph(doc_id="...", anchor="[PLACEHOLDER — DELETE ME]")

docs_append(doc_id, text)

Append a new paragraph at the end of the document.

docs_append(doc_id="...", text="Document last updated: March 2026.")

docs_batch_replace(doc_id, replacements_json)

Apply multiple find→replace operations atomically in a single API call. Either all changes succeed or none do.

docs_batch_replace(
  doc_id="...",
  replacements_json='[
    {"find": "[CLIENT]", "replace": "Acme Corp", "occurrence": 0},
    {"find": "[DATE]", "replace": "10 March 2026", "occurrence": 0},
    {"find": "DRAFT", "replace": "FINAL"}
  ]'
)

Each item in the array:

docs_create(title, initial_text)

Create a new Google Doc.

docs_create(title="Q2 Board Deck", initial_text="Confidential — not for distribution.")

Returns {id, title, webViewLink}.

Suggestions

Suggestions are Docs' tracked changes: the text stays as it is, and the proposed change is shown for the owner to accept or reject. Use them when an agent should propose edits rather than make them (contract redlining, editing someone else's draft).

Pass suggest=true to any editing tool. The arguments and anchors are the same as for a direct edit; the result gains suggested and the suggestion_ids created:

docs_search_replace(doc_id="...", find="14 days", replace="30 days", suggest=true)

{"ok": true, "replaced": "14 days", "at_index": 23, "occurrences_found": 1,
 "suggested": true, "suggestion_ids": ["suggest.abc123"]}

Under the hood this sends the same batchUpdate requests as a direct edit with writeControl.writeMode = "SUGGEST". The Docs API supports that since 30 September 2026 (developer preview from 7 July), with no new scope or dependency.

• Confirmation. A suggest-mode batch can commit its text changes yet fail to save the suggestion, which leaves the edit live with nothing to review. So an edit is only reported as a suggestion when Google names a suggestion it created or changed; otherwise the tool fails with SuggestionNotSavedError, saying the change may have been applied directly.
• Which IDs. suggestion_ids are the suggestions the edit created. If it folded into an existing suggestion (which may be someone else's) that is updated_suggestion_ids, and if it only deleted text a pending suggestion had inserted, a suggestion it shrank away is removed_suggestion_ids. Check docs_list_suggestions for the author before accepting an ID you did not create. Google may also split one edit into several suggestions: an insert with a bullet list comes back as the text and, separately, its list formatting, so review all the IDs returned.
• Attribution. Suggestions are authored by the Google account you authenticated with, as if typed in Suggesting mode.
• Reading. docs_get shows the document as it will read once all suggestions are accepted, so later anchors quote what a reader sees and one edit can build on another.
• Limits. The Docs API refuses some requests in suggest mode: tab changes, named ranges, header/footer deletion, table column properties and a few document-style fields. The editing tools here use none of them.
• Not itemised. Pending changes to tables, images, footnotes, page breaks and the like are listed by docs_list_suggestions with Google's summary, and docs_get flags the paragraphs that hold them, but their changes stay empty.

docs_list_suggestions(doc_id, include_closed)

List the suggestions in a document: who made each, Google's one-line summary, and exactly which text it inserts, deletes or restyles. Covers suggestions people made in the Docs UI as well as ones made with suggest=true. Accepted and rejected ones are left out unless include_closed=true.

{
  "count": 1,
  "suggestions": [{
    "id": "suggest.abc123",
    "status": "OPEN",
    "author": "Dana Smith",
    "created": "2026-10-14T09:00:00Z",
    "summary": "Replace 14 days with 30 days",
    "changes": [
      {"type": "insertion", "text": "30 days", "context": "Payment is due within 30 days of invoice."},
      {"type": "deletion", "text": "14 days", "context": "Payment is due within 30 days of invoice."}
    ],
    "replies": []
  }]
}

type is insertion, deletion, text_style or paragraph_style (both with the fields changed) or bullet. context is the paragraph the change starts in.

docs_review_suggestions(doc_id, action, suggestion_ids)

Accept, reject or delete suggestions, all in one atomic request.

docs_review_suggestions(doc_id="...", action="accept", suggestion_ids=["suggest.abc123"])

Returns ok, action and applied (the IDs Google confirms it processed), plus unconfirmed for any it did not list. If one ID is wrong, none are processed.

Comments

On a Google Doc, comments go through the Docs API: it is the only route Docs shows as anchored to the text (a comment made through Drive reads "Original content deleted").

Word files and PDFs. A .docx uploaded to Drive and opened in Office editing mode is not a Google Doc, and the Docs API refuses comment requests on it (The document must not be an Office file). For any file that is not a Google Doc, all five comment tools fall back to Drive comments on the file, and say so with "source": "drive":

• docs_add_comment cannot anchor the comment, so it starts the comment with a quote of anchor_text and returns "anchored": false. An assignee_email is written at the start of the comment text, because Drive comments cannot be assigned through the API.
• docs_read_comments lists the file's Drive comments in the same shape, each marked "origin": "drive", plus any comments saved inside a Word file, marked "origin": "embedded". The Docs API shows those when it converts the file on the fly; Drive does not list them. Embedded comments are read-only: replying to, resolving or deleting one fails with a message saying so, because neither API can change them. (Convert the file to a Google Doc with docs_convert_to_google_doc to work with them; see below.)
• docs_reply_to_comment, docs_resolve_comment and docs_delete_comment work as usual on Drive comments.

Word files (.docx)

A .docx in Drive can be worked with in part. Converting a copy to a Google Doc gives the full set; the conversion keeps tables, turns Word's tracked changes into suggestions (author and date kept) and turns its comments into ordinary comments.

docs_convert_to_google_doc makes that copy in one call.

docs_convert_to_google_doc(file_id, name)

Make a Google Doc from a Word, RTF, OpenDocument, plain-text, HTML or PDF file in Drive, then use the returned id with every other tool.

docs_convert_to_google_doc(file_id="1BxiMVs0XRA5nFMdKvBdBZjgmUUqptlbs74OgVE2upms")

Returns ok, converted, id (the Google Doc to use from now on), name, webViewLink, converted_from (id, name, type) and a note.

• The original is left alone, and each call makes a new copy beside it.
• A file that is already a Google Doc comes back unchanged (converted: false). A Sheet, image, folder or other type that cannot be a Doc is refused before anything is copied.
• A PDF is converted by text recognition, so expect lost layout and some errors; check it with docs_get.
• It needs the drive scope, which the auth setup already requests.

Drive's own File → Save as Google Docs does the same by hand, and File → Download → Microsoft Word (.docx) converts back. docs_list only lists Google Docs, so pass a Word file's own Drive ID.

docs_add_comment(doc_id, comment, anchor_text, occurrence, assignee_email)

Add a comment anchored to specific text in the document. It shows in the Docs UI as a normal inline highlight on that text. Text inside tables can be anchored too.

Use a short, distinctive phrase for anchor_text — a few words that are unique enough to match exactly one location. The server maps the matched text to its document range and sends a Docs API insertComment request; callers never deal with character indices.

docs_add_comment(
  doc_id="...",
  anchor_text="unable to perform the Employee's duties",
  comment="Legal risk: 3-month absence threshold may not satisfy Equality Act 2010 duty to make reasonable adjustments before terminating."
)

docs_read_comments(doc_id, include_resolved)

List all comments on a document.

Returns count and comments, each with id, content, author, quoted_text (the document text it is anchored to), assignee, resolved, created and replies.

docs_read_comments(doc_id="...")

docs_reply_to_comment(doc_id, comment_id, reply)

Post a reply to an existing comment.

docs_reply_to_comment(
  doc_id="...",
  comment_id="AAAB1iPyaUY",
  reply="Agreed — adding Carer's Leave clause before we sign."
)

docs_resolve_comment(doc_id, comment_id, reply)

Resolve (close) a comment, optionally with a final reply.

docs_resolve_comment(
  doc_id="...",
  comment_id="AAAB1iPyaUY",
  reply="Fixed in v2 — carer's leave clause added at 15.1."
)

docs_delete_comment(doc_id, comment_id)

Permanently delete a comment. Only the comment's author can delete it.

docs_delete_comment(doc_id="...", comment_id="AAAB1iPyaUY")

Typical workflows

Contract review

1. docs_get          — read the document
2. docs_add_comment  — flag issues with anchor_text pointing to specific clauses
3. docs_read_comments — audit what's been flagged
4. docs_search_replace — fix straightforward issues directly
5. docs_resolve_comment — close comments as they're addressed

Bulk document update

1. docs_list         — find all relevant documents
2. docs_batch_replace — apply changes atomically (e.g. rebrand, date update)
3. docs_get          — verify the result

Reviewing a Word contract

1. docs_convert_to_google_doc — a Google Doc copy, with their tracked changes as suggestions and their comments as comments
2. docs_list_suggestions      — see their changes; docs_review_suggestions accepts or rejects each
3. docs_read_comments         — docs_reply_to_comment / docs_resolve_comment to answer them
4. docs_search_replace (suggest=true) — propose your own changes

Redlining (propose changes, don't make them)

1. docs_get              — read the document
2. docs_search_replace / docs_insert_after / ... with suggest=true
3. docs_list_suggestions — check what was proposed
4. (the owner accepts or rejects in Docs — or docs_review_suggestions does it)

Collaborative review

1. docs_add_comment  — add review notes
2. docs_reply_to_comment — respond to collaborator comments
3. docs_resolve_comment  — close resolved threads

Auth environment variables

Legacy GOOGLE_DRIVE_MCP_* env var aliases still work for backward compatibility.
