google-workspace-mcp (laltaffer/google-workspace-mcp) is an MCP server listed on the M8ven Trust Index. M8ven has not graded it: there is no public source to read and no endpoint we can reach, so there is nothing for us to inspect. No publisher has claimed this listing.
Enables read/write access to Google Docs, Sheets, Drive, and Calendar through Claude Desktop, with 24 tools for creating, editing, searching, and managing files and events.
Emerging. No concerning findings. Grades remain capped until the project builds reputation through adoption. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

GOOGLE_CLIENT_ID"": "your-client-id.apps.googleusercontent.com",GOOGLE_CLIENT_SECRET"": "your-client-secret"Tool annotations
No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
20/20 tools missing one or more hints — authorize (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); calendar_list (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); calendar_events (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +17 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Tool inputs are validated
18/20 tool handlers declare input schemas (90%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
19/20 tool handlers wrap calls in try/catch (95%)
Wrap each tool handler body in try/catch and return a structured error response.
License file
No license file
Add a LICENSE file (MIT, Apache-2.0, etc.).
Tool test coverage
Only 0/20 tools referenced in tests (0%)
Write tests that reference each tool by name so every tool has at least one test.
Dev dependencies
2 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
