What this server can do
The server requires authentication before it will list its tools (HTTP 401). We do not hold an account for it, so its functions are unknown to us. The functions below are the last successful declaration, not a fresh answer.
Endpoint status observed on . Source: https://mcp.runcomfy.com/mcp.
10 functions, named and described by the server itself. Parameter names are shown because they say more about what a function does than its name usually does.
call_instance_proxy(instance_id, request_body, deployment_id, comfy_backend_path)- Call 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. Required: deployment_id, instance_id, comfy_backend_path.
cancel_request(request_id, deployment_id)- Cancel 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. Required: deployment_id, request_id.
create_deployment(name, hardware, queue_size, workflow_id, max_instances, min_instances, workflow_version, keep_warm_duration_in_seconds)- Create 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 requests before scaling up. keep_warm_duration_in_seconds: >= 0. Idle timeout. Required: name, workflow_id, workflow_version.
delete_deployment(deployment_id)- Permanently delete a deployment. Backs ``DELETE /prod/v2/deployments/{deployment_id}``. This cannot be undone. Consider ``update_deployment(is_enabled=false)`` to pause instead. Required: deployment_id.
get_deployment(deployment_id, include_readme, include_payload)- Get 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``. Required: deployment_id.
get_request_result(request_id, deployment_id)- Fetch a completed request's outputs. Backs ``GET /prod/v1/deployments/{deployment_id}/requests/{request_id}/result``. Output URLs are hosted for 7 days. Required: deployment_id, request_id.
get_request_status(request_id, deployment_id)- Poll a request's current status. Backs ``GET /prod/v1/deployments/{deployment_id}/requests/{request_id}/status``. Lifecycle: ``in_queue`` → ``in_progress`` → ``completed`` / ``cancelled``. Required: deployment_id, request_id.
list_deployments(ids, include_readme, include_payload)- List 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_request(overrides, extra_data, webhook_url, deployment_id, timeout_seconds, workflow_api_json, wait_for_completion, webhook_intermediate_status)- Submit 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-..."}`` for ComfyUI Core API nodes. webhook_url: Push-based updates instead of polling. webhook_intermediate_status: Fire webhooks on every status change, not just terminal. wait_for_completion: If true, poll until done and return the result inline. timeout_seconds: Max wait when wait_for_completion=true. File inputs: pass a public HTTPS URL or Base64 data URI directly in the overrides value, e.g. ``{"189": {"inputs": {"image": "https://example.com/photo.jpg"}}}`` or ``{"189": {"inputs": {"image": "data:image/jpeg;base64,/9j..."}}}``. Required: deployment_id.
update_deployment(name, hardware, is_enabled, queue_size, deployment_id, max_instances, min_instances, workflow_version, keep_warm_duration_in_seconds)- Partially 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. Required: deployment_id.

Signals
These are separate measurements of different things. They are deliberately not combined into one score, because a popularity number that mixes website traffic with saves and stars cannot be checked or acted on.
