Tools

This server runs locally, so its tools are listed by your MCP client once it starts.

Environment variables

Name	Description
`DESIGN_PATTERN_GENERATOR_API_KEY` Required, secret	API key for the generator LLM (LiteLLM provider).
`DESIGN_PATTERN_GENERATOR_PROVIDER` Optional	LiteLLM provider prefix, e.g. openai, anthropic, openrouter.
`DESIGN_PATTERN_GENERATOR_MODEL` Optional	Model name, combined as <provider>/<model> via LiteLLM.
`DESIGN_PATTERN_GENERATOR_BASE_URL` Optional	OpenAI-compatible base URL (LiteLLM api_base).
`DESIGN_PATTERN_PATTERN_DIRECTORY` Optional	Directory with the catalog records (*.json main records plus per-language files). The image bakes the 438-record catalogue at /app/pattern.
`DESIGN_PATTERN_EMBEDDER_BASE_URL` Required	Required: the dense retrieval leg embeds the 438-record catalogue during startup warmup and the server refuses to start when the endpoint is unreachable. TEI embeddings endpoint: on the Docker host use http://host.docker.internal:8080 (add --add-host=host.docker.internal:host-gateway on Linux); on…
`DESIGN_PATTERN_EMBEDDER_API_KEY` Optional, secret	API key for the embedder. Keyless TEI accepts any non-empty value; use 'not-needed' there.
`DESIGN_PATTERN_RERANKER_BASE_URL` Required	Required: retrieval runs a mandatory TEI cross-encoder rerank whenever the fused pool has more than one candidate. On the Docker host use http://host.docker.internal:8080; on a shared Docker network use http://design-pattern-tei-rerank:8080.
