Temporal MCP
Durable execution for agents. Start workflows, signal running executions, query state. Best-in-class reliability for long-running agent tasks.
Solid choice for most workflows
You need agent tools that survive crashes, network failures, and long waits—without losing state or duplicating work mid-execution.
Bulletproof reliability for mission-critical agent tasks. Trade-off: added latency from Temporal's event sourcing and replay overhead (typically milliseconds to seconds per tool call). Observability is exceptional—full audit trail and replay in Temporal UI. Best for tools that call external APIs, wait for approvals, or orchestrate multi-step processes.
You're building agents that coordinate multiple external systems (GitHub, Jira, CI/CD, APIs) and need to guarantee each step completes or fails atomically—no partial states.
Seamless orchestration of 5–50+ step workflows. Each Activity can retry independently with custom policies. Full visibility in Temporal UI. Caveat: Workflows must be deterministic (no random numbers, timestamps in business logic). Learning curve for Temporal's replay semantics.
Your agent tools need to handle long-running, interactive processes—like waiting days for human approval, polling for async job completion, or managing stateful conversations.
True long-duration tools (days/weeks) that don't consume resources while waiting. Agents can check status or send commands to running workflows. Complexity: managing Signal/Query semantics and ensuring idempotency across replays.
Determinism requirement constrains tool logic
Temporal Workflows must be deterministic for replay to work correctly. Non-deterministic code (random numbers, external timestamps, uncontrolled API calls) can cause replay divergence and silent failures. You must wrap all non-deterministic operations as Activities.
Temporal Server deployment and operational overhead
Temporal MCP requires a running Temporal Server (cluster or cloud-managed). Self-hosting adds operational burden (monitoring, upgrades, backups). Cloud options (Temporal Cloud) reduce ops but add cost and vendor lock-in. Not suitable for simple, stateless tools.
Trust Breakdown
What It Actually Does
Temporal MCP lets AI agents reliably start, check on, and interact with long-running workflows that keep going even if something crashes. It handles retries, timeouts, and state for tasks like approvals or trades that take hours or days.[1][2][3][5]
