Gemini MCP Server (Raindancer118/gemini-mcp) is an MCP server listed on the M8ven Trust Index. M8ven has not graded it: we have no way to read this server ourselves. No publisher has claimed this listing.
Integrates Google Gemini's capabilities—including search-grounding, image/video generation, deep research, and SVG creation—into AI assistants like Claude via the Model Context Protocol.
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.

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
21/21 tools missing one or more hints — gemini_help (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); gemini_prompt_assistant (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); gemini_agent (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +18 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
19/21 tool handlers declare input schemas (90%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
19/21 tool handlers wrap calls in try/catch (90%)
Wrap each tool handler body in try/catch and return a structured error response.
Tool test coverage
Only 2/21 tools referenced in tests (10%)
Write tests that reference each tool by name so every tool has at least one test.
Shell command execution
2 child_process calls — runs shell commands
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Dev dependencies
2 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
Domain consistency
npm scope @houtini doesn't match GitHub owner raindancer118
Use the same org name across GitHub, npm, and your homepage so users can verify the publisher.
