# CognitionAcp.CognitionMcpToolMeta

> Metadata for events — calls to MCP tools like , , or third-party MCP.

Metadata for `mcp_tool_call` events — calls to MCP tools like
`devin_knowledge_manage`, `devin_session_create`, or third-party MCP.

Discriminated by the required `tool_name` field: only `mcp_tool_call`
events carry `cognition.ai/toolName`.

```typescript
type CognitionMcpToolMeta = void
```
