Remote MCP server for RunComfy Serverless API (ComfyUI): deployments and async inference.
* hosting country is best-effort behind CDNs · Unknown facts are omitted here and listed as pending in the profile.
Trust verdict
No blockers found across the assessed dimensions.
Profile
What this server is — descriptive, not a rating. The verdict above judges it; this describes it.
Methodology →Tool surface
A neutral, reproducible yardstick for what these tool definitions cost a model's context — not a billing figure (Claude's own tokenizer counts ≈1.1–1.2× this).
Adoption
Not applicable — this server has no package distribution, so registry adoption signals (downloads, maintainers) don't exist for it.

Every verdict and label is attributable to its source and recomputed from our own landed copy, never read live on this page.
call_instance_proxyCall a ComfyUI backend endpoint on a live instance. Backs ``POST /prod/v2/deployments/{deployment_id}/instances/{instance_id}/proxy/{path}``. Get the instance_id from ``get_request_status`` once the status is ``in_progress``. Common target: ``api/free`` with ``{"unload_models": true}`` to free GPU memory.
cancel_requestCancel a queued or running request. Backs ``POST /prod/v1/deployments/{deployment_id}/requests/{request_id}/cancel``. Returns ``cancelled`` if accepted, ``not_cancellable`` if already done.
create_deploymentCreate a Serverless API (ComfyUI) deployment. Backs ``POST /prod/v2/deployments``. For LoRA deployments, create via the runcomfy.com UI instead. Args: name: Human-readable name. workflow_id: UUID of the ComfyUI workflow. workflow_version: Version label, e.g. "v1". hardware: One of TURING_16, AMPERE_24, AMPERE_48, ADA_48_PLUS, AMPERE_80, ADA_80_PLUS, HOPPER_141. min_instances: 0..30. Warm instance floor (billable if > 0). max_instances: 1..60. Concurrency ceiling. queue_size: >= 0. Pending reques…
delete_deploymentPermanently delete a deployment. Backs ``DELETE /prod/v2/deployments/{deployment_id}``. This cannot be undone. Consider ``update_deployment(is_enabled=false)`` to pause instead.
get_deploymentGet one deployment by ID. Backs ``GET /prod/v2/deployments/{deployment_id}``. Set include_payload=true to inspect the deployed workflow graph (workflow_api_json) and default overrides — use the node IDs and input names to build the ``overrides`` for ``submit_request``.
get_request_resultFetch a completed request's outputs. Backs ``GET /prod/v1/deployments/{deployment_id}/requests/{request_id}/result``. Output URLs are hosted for 7 days.
get_request_statusPoll a request's current status. Backs ``GET /prod/v1/deployments/{deployment_id}/requests/{request_id}/status``. Lifecycle: ``in_queue`` → ``in_progress`` → ``completed`` / ``cancelled``.
list_deploymentsList Serverless API deployments in the caller's account. Backs ``GET /prod/v2/deployments``. Args: ids: Optional list of deployment IDs to filter to. include_payload: Include workflow_api_json, overrides, and object_info_url for each deployment. Larger response. include_readme: Include the deployment's README markdown.
submit_requestSubmit an async inference request to a deployment. Backs ``POST /prod/v1/deployments/{deployment_id}/inference``. Args: deployment_id: Target deployment. overrides: Partial graph keyed by node_id, e.g. ``{"6": {"inputs": {"text": "a cat"}}}``. Use ``get_deployment(include_payload=true)`` to discover node IDs and input names. workflow_api_json: Advanced — run a different workflow without updating the deployment. Omit ``overrides`` in this mode. extra_data: E.g. ``{"api_key_comfy_org": "comfyui-..…
update_deploymentPartially update a deployment. Backs ``PATCH /prod/v2/deployments/{deployment_id}``. Only pass the fields you want to change. Set is_enabled=false to pause; true to re-enable.
