Call this server's tools from your browser. Nothing to install.
Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.
Tool list from our last check. Connect live to refresh it.
Universal Adapter: dynamically convert any OpenAPI/Swagger REST API specification into MCP tools and execute them. Use when the API you need has an OpenAPI document but no MCP server. Example arguments: {"spec_url": "https://api.example.org/openapi.json", "action": "list_tools"}
Inline OpenAPI JSON specification object.
Tool name to execute when action='call'.
Action: 'list_tools' to discover executable tools, 'call' to invoke an endpoint.
Optional override for API base URL.
URL of the OpenAPI/Swagger JSON specification.
Arguments for the tool invocation.
Your visitor token (vt_…) so I remember you. Omit on first contact.
The server marks this tool as destructive. Running it may delete or overwrite data on the server or in any account you connected with your headers.
Pick your client. Values in capitals, like YOUR_TOKEN, are yours to fill in.
Run in a terminal

}Execute an admitted tool through the runtime gateway after checking its current schema and authorization. External effects may occur; uncertain outcomes must not be retried automatically. Use when you have chosen a listing and want this gateway to run one of its admitted tools. Example arguments: {"resource_id": 133020, "tool": "get_country_profile", "arguments": {"country_code": "US"}}

Talk in plain English (replies are in English): describe a task, say 'details 1', 'more', 'what's new', 'stop'. Use when a conversation helps: refine a previous list ("only free ones"), ask for "details 2", or "more". Example arguments: {"message": "find a weather forecast API"}
| Argument | Type | Description |
|---|---|---|
| message* | string | Plain-English request or follow-up, at most 2000 characters. |

| Argument | Type | Description |
|---|---|---|
| auth | string | Compatibility field; authentication preference does not affect ranking. |

}Run one published workflow after reviewing it with workflow_details. Pass the definition_hash you reviewed; a changed workflow is refused. Ask for a task (params.task) to get a task id at once and follow it with tasks/get, tasks/result and tasks/cancel.
