claude mcp add recall-rag -e RECALL_SERVING_DSN='<recall-serving-dsn>' -- uvx recall-rag

{
  "mcpServers": {
    "recall-rag": {
      "command": "uvx",
      "args": [
        "recall-rag"
      ],
      "env": {
        "RECALL_SERVING_DSN": "<recall-serving-dsn>"
      }
    }
  }
}

Add to ~/.cursor/mcp.json (global) or .cursor/mcp.json (project).

{
  "mcpServers": {
    "recall-rag": {
      "command": "uvx",
      "args": [
        "recall-rag"
      ],
      "env": {
        "RECALL_SERVING_DSN": "<recall-serving-dsn>"
      }
    }
  }
}

Settings → Developer → Edit Config (claude_desktop_config.json), then restart.

{
  "servers": {
    "recall-rag": {
      "type": "stdio",
      "command": "uvx",
      "args": [
        "recall-rag"
      ],
      "env": {
        "RECALL_SERVING_DSN": "<recall-serving-dsn>"
      }
    }
  }
}

Add to .vscode/mcp.json in your workspace.

{
  "mcpServers": {
    "recall-rag": {
      "command": "uvx",
      "args": [
        "recall-rag"
      ],
      "env": {
        "RECALL_SERVING_DSN": "<recall-serving-dsn>"
      }
    }
  }
}

Add to ~/.codeium/windsurf/mcp_config.json.

Configuration

Variable	Required	Secret	Description
RECALL_SERVING_DSN	yes	yes	PostgreSQL serving DSN for the RE-call memory store.
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, for example voyage:voyage-4 or BAAI/bge-large-en-v1.5. It must match: several models emit 1024 dimensions, so a mismatch does not error, it returns a confidently ranked list that means nothing.
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.
