Tools
This server runs locally, so its tools are listed by your MCP client once it starts.
Environment variables
| Name | Description |
|---|---|
BASE_URLRequired | Absolute http(s) API root prefix; the SDK appends /v1/systemone. Required at startup with no provider default or host allowlist; custom path prefixes are supported. Must not include credentials, a query or a fragment. |
MODELRequired | Default model name sent to the configured endpoint. Required at startup with no default or model allowlist; a per-call model argument overrides it and a blank per-call override is rejected. |
API_KEYOptional, secret | API credential for the configured endpoint, sent as a Bearer token. Optional at startup (tool discovery works without it); decision calls require it and return MISSING_API_KEY until it is set. |
JEV_TIMEOUT_MSOptional | Total request deadline in milliseconds, including automatic SDK retries (1–120000) |
