| NCBI_API_KEY | No | Optional API key for PubMed/NCBI to raise rate limit from 3 to 10 requests per second. | |
| OPENAI_API_KEY | No | API key for OpenAI, required if using OpenAI embedder (RESEARCH_MCP_EMBEDDER starts with 'openai') or analysis model (RESEARCH_MCP_ANALYSIS_MODEL starts with 'openai'). | |
| RESEARCH_MCP_EMBEDDER | No | Embedder to use for vector embeddings. Format: 'provider:model', e.g., 'openai:text-embedding-3-small' or 'sentence-transformers:BAAI/bge-base-en-v1.5'. Required for library ingest and recall. | |
| RESEARCH_MCP_RERANKER | No | Optional cross-encoder reranker for improved search quality. Format: 'cross-encoder:model', e.g., 'cross-encoder:BAAI/bge-reranker-base'. | |
| RESEARCH_MCP_INDEX_PATH | No | File path to store the FAISS index and metadata. Required for library tools (ingest, library_search, etc.). | |
| RESEARCH_MCP_DISABLE_PDF | No | Set to '1' to disable PDF full-text extraction during ingest even if pdfplumber is installed. | |
| SEMANTIC_SCHOLAR_API_KEY | No | Optional API key for Semantic Scholar to raise rate limits. | |
| RESEARCH_MCP_ANALYSIS_MODEL | No | LLM model for paper analysis (analyze_paper tool). Format: 'provider:model', e.g., 'openai:gpt-4o-mini' or 'anthropic:claude-haiku-4-5-20251001'. Required for analyze_paper. | |
| RESEARCH_MCP_DISABLE_PUBMED | No | Set to '1' to disable PubMed as a search source (default: enabled). | |
| RESEARCH_MCP_OPENALEX_EMAIL | No | Email address to identify with OpenAlex API (optional but good practice). | |
| RESEARCH_MCP_CITATION_SCORER | No | Optional LLM-based citation scorer to override the default heuristic scorer. Format: 'llm:provider:model', e.g., 'llm:anthropic:claude-haiku-4-5-20251001'. | |
| RESEARCH_MCP_CLAIM_EXTRACTOR | No | Optional LLM-based claim extractor to override the default spaCy extractor. Format: 'llm:provider:model', e.g., 'llm:anthropic:claude-haiku-4-5-20251001'. | |
