Connecting OpenClaw Agent to Sphene via Native MCP

To connect OpenClaw to Sphene, configure Sphene as a Stdio MCP server in your OpenClaw configuration targeting sphene mcp with SPHENE_URL=http://127.0.0.1:8743. OpenClaw gains sub-millisecond search, AST section patching, and secure partitioned storage under 25MB RAM without shell pipe errors.

OpenClaw Configuration (openclaw.json)

Add the Sphene MCP server to your OpenClaw workspace tool configuration: 

{
  "mcpServers": {
    "sphene": {
      "command": "/usr/local/bin/sphene",
      "args": ["mcp"],
      "env": {
        "SPHENE_URL": "http://127.0.0.1:8743"
      }
    }
  }
}

  • sphene_find_in_doc: Pinpoint exact facts or code blocks in large documents without context window exhaustion.
  • sphene_patch: Atomically update headings and task checklists with automatic diff folding.
