Install amu-pgvector MCP server

claude mcp add amu-pgvector -e AMU_PGVECTOR_DSN='<amu-pgvector-dsn>' -- uvx amu-pgvector amu-pgvector-mcp

{
  "mcpServers": {
    "amu-pgvector": {
      "command": "uvx",
      "args": [
        "amu-pgvector",
        "amu-pgvector-mcp"
      ],
      "env": {
        "AMU_PGVECTOR_DSN": "<amu-pgvector-dsn>"
      }
    }
  }
}

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

{
  "mcpServers": {
    "amu-pgvector": {
      "command": "uvx",
      "args": [
        "amu-pgvector",
        "amu-pgvector-mcp"
      ],
      "env": {
        "AMU_PGVECTOR_DSN": "<amu-pgvector-dsn>"
      }
    }
  }
}

        "amu-pgvector",
        "amu-pgvector-mcp"
      ],
      "env": {
        "AMU_PGVECTOR_DSN": "<amu-pgvector-dsn>"
      }
    }

Configuration

Variable	Required	Secret	Description
AMU_PGVECTOR_DSN	yes	yes	Postgres DSN for the role this server runs as. Results are gated by row-level security under this exact role -- use an amu_writer-member role for amu_record/amu_check_conflict, or an amu_agent_base-member role for read-only amu_search.
AMU_PGVECTOR_EMBEDDING_DIM	—	—	Embedding vector dimension, used only by the built-in deterministic fallback embedder when sentence-transformers (the amu-pgvector[st] extra) isn't installed. Must match the dimension sql/amu_pgvector.sql was installed with. Default: 1536.
