Created automatically if it does not exist. · 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_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. · 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_TRANSFORM_CACHE_SIZE=Maximum number of transformed image results (resize, crop, convert) kept in memory.

2026-08-16Beschreibungen der Umgebungsvariablen (Rohangabe): – → FASTMCP_LOG_LEVEL=Log level for FastMCP internals; app loggers default to INFO, -v overrides both to DEBUG. · IMAGE_GENERATION_MCP_A1111_HOST=Deprecated — use SD_WEBUI_HOST instead. Accepted as fallback. · IMAGE_GENERATION_MCP_A1111_MODEL=Deprecated — use SD_WEBUI_MODEL instead. Accepted as fallback. · IMAGE_GENERATION_MCP_AUTH_MODE=OIDC auth mode: 'remote' (JWKS validation) or 'oidc-proxy' (OAuth proxy). Auto-detected if not set. · IMAGE_GENERATION_MCP_BASE_URL=Public base URL for OIDC redirects (e.g. https://mcp.example.com). Required for OIDC. · IMAGE_GENERATION_MCP_BEARER_TOKEN=Static bearer token for HTTP authentication. · IMAGE_GENERATION_MCP_DEFAULT_PROVIDER=Default provider selection: auto (keyword-based), openai, sd_webui, or placeholder. Deprecated alias 'a1111' is also accepted. · IMAGE_GENERATION_MCP_EVENT_STORE_URL=EventStore backend for SSE session resumability. file:///path (file-backed, survives restarts) or memory:// (in-process only, dev mode). · IMAGE_GENERATION_MCP_HTTP_PATH=HTTP endpoint mount path for streamable-HTTP transport. · IMAGE_GENERATION_MCP_INSTRUCTIONS=System-level instructions injected into LLM context. · IMAGE_GENERATION_MCP_KV_STORE_URL=Persistent-state backend URL for pvl-core subsystems. Schemes: file:///path (survives restarts), memory:// (dev/ephemeral). · IMAGE_GENERATION_MCP_OIDC_AUDIENCE=Expected JWT audience claim. Leave unset if your provider does not set one. · IMAGE_GENERATION_MCP_OIDC_CLIENT_ID=OIDC client ID. Required for OIDC. · IMAGE_GENERATION_MCP_OIDC_CLIENT_SECRET=OIDC client secret. Required for OIDC. · IMAGE_GENERATION_MCP_OIDC_CONFIG_URL=OIDC discovery endpoint URL. Required for OIDC. · IMAGE_GENERATION_MCP_OIDC_JWT_SIGNING_KEY=Signing key for OIDC session JWTs (critical on Linux/Docker). · IMAGE_GENERATION_MCP_OIDC_REQUIRED_SCOPES=Comma-separated required OIDC scopes (default: openid for oidc-proxy mode, none for remote mode). · IMAGE_GENERATION_MCP_OIDC_VERIFY_ACCESS_TOKEN=Verify access token JWT instead of id_token. · IMAGE_GENERATION_MCP_OPENAI_API_KEY=OpenAI API key. Enables the OpenAI provider (gpt-image-1, dall-e-3) when set. · IMAGE_GENERATION_MCP_READ_ONLY=When true, write-tagged tools (generate_image) are hidden. Set to false to enable image generation. · IMAGE_GENERATION_MCP_SCRATCH_DIR=Directory for saved generated images inside the container. · IMAGE_GENERATION_MCP_SCRATCH_DIR=Directory for saved generated images. Created automatically on first use. · IMAGE_GENERATION_MCP_SD_WEBUI_HOST=SD WebUI base URL (e.g. http://localhost:7860). Enables the SD WebUI provider when set. · IMAGE_GENERATION_MCP_SD_WEBUI_MODEL=SD WebUI checkpoint name for model-aware preset detection (SD 1.5 vs SDXL vs Lightning vs Flux). · IMAGE_GENERATION_MCP_SERVER_NAME=Server name shown to MCP clients in the initialization response. · PGID=Run as this GID (Docker entrypoint). · PUID=Run as this UID (Docker entrypoint).
