Temporal MCP Server (Official)
Official Temporal MCP server enabling AI agents to interact with Temporal's workflow orchestration platform — querying workflow executions, signaling workflows, inspecting workflow state, and managing task queues.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
HTTPS enforced. mTLS for self-hosted is enterprise-grade. Namespace-level isolation. SOC 2 Type II, ISO 27001. Strong workflow security.
⚡ Reliability
Best When
An agent needs to inspect, signal, or manage workflows running in a Temporal cluster — especially for operational monitoring or incident response.
Avoid When
You're using Airflow, Prefect, Dagster, or other workflow engines.
Use Cases
- • Querying workflow execution status from monitoring and operations agents
- • Signaling workflows to pause, resume, or inject data from automation agents
- • Investigating failed workflow executions for debugging agents
- • Managing task queue health and worker status via agents
- • Querying workflow history for audit and compliance agents
Not For
- • Teams not using Temporal for workflow orchestration
- • Simple job queues (use Celery, BullMQ, etc.)
- • Non-Temporal workflow engines (Airflow, Prefect, etc.)
Interface
Authentication
Temporal Cloud uses API keys. Self-hosted supports mTLS and OIDC. Namespace-based isolation provides access boundaries.
Pricing
Temporal OSS is free and self-hostable. Cloud provides managed infrastructure. Per-action pricing on cloud.
Agent Metadata
Known Gotchas
- ⚠ Namespace required for all operations — always scope to correct namespace
- ⚠ Workflow ID + Run ID pair uniquely identifies a workflow execution
- ⚠ Workflow history can be very large — use pagination for long-running workflows
- ⚠ Signaling workflows is a mutation — implement confirmation before sending signals
- ⚠ mTLS setup for self-hosted is complex — plan for auth configuration complexity
- ⚠ Temporal SDK vs API are different interaction models — MCP uses HTTP/gRPC API
