fastcar-vision (williamDazhangyu/-fastcar-mcp-vision-tools) 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.
Provides vision understanding capabilities such as image analysis, OCR, object localization, and video frame analysis, plus optional image generation and editing, to coding agents via OpenAI-compatible multimodal models. Runs as a local MCP server with HTTP and stdio transports, configurable for clients like Codex, Claude Code, Kimi, and Cursor.
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.

6/9 tools missing one or more hints — analyze_image (missing: destructiveHint, idempotentHint); analyze_video (missing: destructiveHint, idempotentHint); list_vision_models (missing: destructiveHint, idempotentHint), +3 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
Only 2/9 tool handlers declare input schemas (22%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
Only 2/9 tool handlers wrap calls in try/catch (22%)
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.).
Tests exist
No test files found
Add tests that exercise each declared tool.
Shell command execution
2 child_process/subprocess calls in production code — runs shell commands (src/daemon.ts:242, src/media/video.ts:54)
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
No arbitrary install scripts
Has postinstall/preinstall script — runs arbitrary code on npm install
Remove postinstall/preinstall hooks unless they’re essential.
Domain consistency
npm scope @fastcar doesn't match GitHub owner williamdazhangyu
Use the same org name across GitHub, npm, and your homepage so users can verify the publisher.
