MCP tool

list_buyer_sessions

Read compact summaries of persisted buyer sessions belonging to this authenticated agent client, tenant and product scope. Use get_buyer_session to recover a selected conversation.

Input

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

Input JSON Schema
{
  "$schema": "https://json-schema.org/draft/2020-12/schema",
  "type": "object",
  "properties": {
    "limit": {
      "type": "integer",
      "minimum": 1,
      "maximum": 100
    }
  },
  "additionalProperties": false
}

REST mapping and authority

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

Request contract
{
  "method": "GET",
  "path": "/api/v1/buyer/sessions",
  "pathFields": [],
  "pathSchema": {
    "type": "object",
    "properties": {},
    "additionalProperties": false
  },
  "pathEncoding": "encodeURIComponent for each path field",
  "governedAction": null,
  "headers": {},
  "querySchema": {
    "type": "object",
    "properties": {
      "limit": {
        "type": "integer",
        "minimum": 1,
        "maximum": 100
      }
    },
    "additionalProperties": false
  },
  "queryEncoding": "URLSearchParams; omit undefined fields, stringify supplied values",
  "responseMapping": "REST JSON is returned as MCP structuredContent and a compatibility text block; privacy-sensitive tools validate their output schema."
}

Output

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

Output JSON Schema
{
  "$schema": "https://json-schema.org/draft/2020-12/schema",
  "type": "object",
  "properties": {},
  "additionalProperties": {}
}

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 →
