RE Call MCP Memory Server

Host a copy with our keys and logs.

• RECALL_SERVING_DSN — The store RE-call reads: a PostgreSQL DSN, or the sqlite:/// address `recall setup --lite` prints for a local Lite store with no database server.
• RECALL_TENANT — Tenant id served by this local stdio server.
• RECALL_TRUST_MODE — Set to development only for local uncalibrated corpora.
• RECALL_EMBEDDER — The embedder the corpus was BUILT with. This registry command installs FastEmbed: use fastembed or a supported FastEmbed model such as BAAI/bge-large-en-v1.5. A Voyage corpus requires a separate launch installed with recall-rag[mcp,voyage] and its API key. The model must match the corpus even when dimensions agree.
• RECALL_TABLE — The chunk table inside that database. `recall quickstart` indexes into quickstart_chunks so its sample corpus can never be retrieved beside real memory; `recall setup` uses chunks. The wrong value returns no hits and no error.
• RECALL_MCP_TOOLS — Optional. Serve a subset of the tools: a preset (all, search, read) or explicit names. Every tool definition is re-sent every turn, so serving ones nobody calls costs input tokens on every turn. Unset serves them all.
