# ApiExecFn

**Kind:** Type

**Source:** [`atloria-monorepo/libs/parser-core/src/techdocs/mcp-toolset.ts`](https://github.com/sherkety/atloria/blob/main/atloria-monorepo/libs/parser-core/src/techdocs/mcp-toolset.ts#L43)

Optional live-API execution backend. Injected the same way as askFn so the toolset stays PURE
(no fetch/dns/Nest here) — all outbound HTTP, SSRF validation, method allow-listing and
server-side auth injection live in the executor the API layer builds (api-executor.ts). Present
only when the project has opted into a Live API target, which is what gates the `call_operation`
tool below.
