invoke_function
InactiveTool of io.github.butterbase-ai/mcp
Invoke a deployed function and return its full HTTP response. Example — POST with body: Input: { app_id: "app_abc123", function_name: "submit-inquiry", body: { email: "user@example.com", message: "hello" } } Output: { status: 200, headers: { "content-type": "application/json" }, body: { id: "uuid-1234" }, duration_ms: 47 } Example — GET (no body): Input: { app_id: "app_abc123", function_name: "public-catalog", method: "GET" } Parameters: - method defaults to POST. The function's trigger config determines which methods are valid. - body is sent as JSON. Omit for GET/HEAD requests. - headers are merged with the default auth headers. Use this to: - Test a function immediately after deployment - Debug function logic with different inputs - Verify function response format and status codes Common errors: - RESOURCE_NOT_FOUND: Function doesn't exist, use manage_function (action: "list") to verify - Function timeout: Increase timeoutMs in deploy_function - Runtime error: Check manage_function (action: "get_logs") for stack trace Idempotency: Depends on function implementation (may have side effects).
