MCP tool

get_buyer_context

Start or resume one of four buying workflows. Reads scoped resource evidence, missing inputs, human handoffs and exact canonical next-tool arguments. Does not launch, spend, generate assets or approve actions.

Input

Pass fields from this schema as the tool arguments. Runtime ownership, product scope and readiness checks still apply.

REST mapping and authority

The tool wraps this REST endpoint. The mapping identifies path/query/body transformations and approval or idempotency headers.

Output

This is the registered MCP output envelope. Nested fields are only modeled where the schema explicitly defines them.

Safety annotations

MCP annotations

{
  "readOnlyHint": true,
  "destructiveHint": false,
  "idempotentHint": false,
  "openWorldHint": false
}

Annotations help a client present the tool. The API independently enforces authorization and exact action approvals. Error and retry guidance →
