Package (pypi 0.4.1)

uvx perenna

Or add to your MCP client config:

{
  "mcpServers": {
    "perenna": {
      "command": "uvx",
      "args": [
        "perenna"
      ],
      "env": {
        "VEXOR_API_KEY": "<YOUR_VALUE>",
        "VEXOR_REMOTE_RERANK_API_KEY": "<YOUR_VALUE>"
      }
    }
  }
}

PERENNA_GIT_REMOTE — Git remote name used for optional synchronization (for example, origin); leave unset for local-only operation
VEXOR_API_KEY secret — Embedding provider API key (optional; overrides a stored key; providers can also be configured via `vexor init`)
VEXOR_REMOTE_RERANK_API_KEY secret — Remote reranker API key (optional; overrides a stored key; only needed when rerank is set to remote)
VEXOR_CONFIG_JSON — Non-secret Vexor config as a JSON object, e.g. {"provider": "gemini", "rerank": "bm25"} (optional; merged over ~/.vexor/config.json; credential fields are rejected, use the dedicated variables)
