What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Connect this server

This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

This one needs environment variables set before it will start: IMAGE_GENERATION_MCP_KV_STORE_URL (Persistent-state backend URL shared by every pvl-core subsystem that needs state. `memory://` is in-process and lost on restart; `file:///path` persists on one server; `redis://`, `dynamodb://` and `mongodb://` each need their matching extra. When unset, defaults to `file:///data/state` (the volume family Docker images mount), or to `memory://` — with a warning — on a host where that directory is not usable.), IMAGE_GENERATION_MCP_TOOLS_ALLOW (Comma-separated explicit tool names this instance exposes; every other tool is hidden from listings and cannot be invoked. Names matching no registered tool are inert. Mutually exclusive with `tools_deny`. Takes effect through `apply_tool_visibility`.), IMAGE_GENERATION_MCP_TOOLS_DENY (Comma-separated explicit tool names hidden from this instance (absent from listings, cannot be invoked). Names matching no registered tool are inert. Mutually exclusive with `tools_allow`. Takes effect through `apply_tool_visibility`.), IMAGE_GENERATION_MCP_SERVER_NAME (Rename this server instance; defaults to the project name.), IMAGE_GENERATION_MCP_INSTRUCTIONS (Replaces the default MCP instructions text sent to clients.), FASTMCP_LOG_LEVEL (Log level for FastMCP internals and app loggers (DEBUG / INFO / WARNING / ERROR / CRITICAL). The -v CLI flag overrides to DEBUG.), FASTMCP_ENABLE_RICH_LOGGING (Set false for plain or structured JSON log output.), IMAGE_GENERATION_MCP_A1111_HOST (Deprecated alias for IMAGE_GENERATION_MCP_SD_WEBUI_HOST; logs a warning when used.), IMAGE_GENERATION_MCP_A1111_MODEL (Deprecated alias for IMAGE_GENERATION_MCP_SD_WEBUI_MODEL; logs a warning when used.), IMAGE_GENERATION_MCP_READ_ONLY (When true, write-tagged tools (image generation, transforms, uploads) are hidden from clients. Set false to enable them.), IMAGE_GENERATION_MCP_SCRATCH_DIR (Directory where generated images are saved. Created automatically on first use.), IMAGE_GENERATION_MCP_OPENAI_API_KEY (OpenAI API key. Enables the OpenAI provider (gpt-image-2, gpt-image-1.5, dall-e-3) when set.), IMAGE_GENERATION_MCP_GOOGLE_API_KEY (Google API key. Enables the Gemini provider (gemini-3.1-flash-image and others) when set. Get a key at https://aistudio.google.com/apikey.), IMAGE_GENERATION_MCP_SD_WEBUI_HOST (SD WebUI base URL (such as http://localhost:7860). Enables the SD WebUI provider when set. Compatible with AUTOMATIC1111, Forge, reForge, and Forge-neo.), IMAGE_GENERATION_MCP_SD_WEBUI_MODEL (SD WebUI checkpoint name, used for model-aware preset detection (SD 1.5 / SDXL / Lightning) and checkpoint override. Unset uses the instance's current model.), IMAGE_GENERATION_MCP_DEFAULT_PROVIDER (Provider used when no keyword triggers auto-selection: auto, openai, gemini, sd_webui, or placeholder. auto picks the first configured provider.), IMAGE_GENERATION_MCP_TRANSFORM_CACHE_SIZE (Maximum number of transformed image results (resize, crop, convert) kept in memory. Set 0 to disable caching.), IMAGE_GENERATION_MCP_PAID_PROVIDERS (Comma-separated provider names that cost money; generate_image asks for confirmation (client elicitation) before using them. An empty value falls back to this default; to disable confirmation, set a value that names no provider (such as none).), IMAGE_GENERATION_MCP_STYLES_DIR (Directory for style preset files (Markdown with YAML front matter). Created automatically if it does not exist.), IMAGE_GENERATION_MCP_ALLOW_LOCAL_FILE_INPUT (Allow reading input images from local filesystem paths. Off by default: only URLs and uploads are accepted.), IMAGE_GENERATION_MCP_MAX_INPUT_IMAGE_BYTES (Maximum accepted input image size in bytes.), IMAGE_GENERATION_MCP_FETCH_TIMEOUT_S (HTTP timeout in seconds when fetching remote image URLs (fetch_image and URL inputs).), IMAGE_GENERATION_MCP_TRANSFER_TTL_DEFAULT_S (Link lifetime in seconds when the caller requests no explicit TTL.), IMAGE_GENERATION_MCP_TRANSFER_TTL_MAX_S (Ceiling in seconds a caller-requested link TTL is clamped to.), IMAGE_GENERATION_MCP_TRANSFER_GRACE_TTL_S (Post-success grace window in seconds: a served token's TTL shrinks to this so a stalled transfer can retry within it.), IMAGE_GENERATION_MCP_TRANSFER_LEASE_S (Crashed-handler reclaim window in seconds for an in-flight reservation.), IMAGE_GENERATION_MCP_TRANSFER_MAX_UPLOAD_BYTES (Maximum size in bytes of a single upload.). The author declared them in the registry entry; get the values from the project itself.
