gemini-image-mcp
MCP server that generates images using Gemini models via an OpenAI-compatible gateway.
Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.
generate_image通过 OpenAI-compatible 接口调用 Gemini 的 "gemini-3-pro-image-preview" 生成图片：默认保存到本地并返回文件路径（避免 base64 导致 token 暴涨）；也可用 output=image 返回 MCP image content。
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
@modelcontextprotocol/sdk has cross-client data leak via shared server/transport instance reuse
Anthropic's MCP TypeScript SDK has a ReDoS vulnerability
GEMINI_API_KEYOPENAI_API_KEY：如果你的网关需要鉴权就填（可留空）OPENAI_BASE_URL：OpenAI-compatible 服务地址（默认 http://127.0.0.1:8317）OPENAI_DEBUG：设为 1 时会在 stderr 打印上游请求信息（不打印 key）OPENAI_IMAGE_MODE：chatimagesauto，默认 chat（CLIProxyAPI 这类网关通常用 /v1/chat/completions 出图；若你的网关支持 /v1/images/generations 可设为 images）OPENAI_IMAGE_OUT_DIR：保存目录（默认 debug-output/；相对路径以项目根目录为基准）OPENAI_IMAGE_RETURN：pathimage，默认 path（path 会把图片保存到本地并返回文件路径，避免 base64 导致 token 暴涨；image 返回 MCP image content）OPENAI_IMAGE_SIZE：可选，仅作为未传入 size 时的默认值；建议让客户端在调用 generate_image 时自己传 sizeOPENAI_MODEL：默认 gemini-3-pro-image-previewOPENAI_TIMEOUT_MS：默认 120000Tool 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
1/1 tools missing one or more hints — generate_image (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint). 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.
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 calls — runs shell commands
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Production dependencies are patched
0 critical, 2 high severity in production deps — @modelcontextprotocol/sdk@1.25.1 (high), @modelcontextprotocol/sdk@1.25.1 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
