mcp-3xui

MCP server for the 3x-ui panel API (v3.7+).

Recent panel versions treat a client as a global object attached to many inbounds. MCP servers written against the older per-inbound API cannot express that, so operations like "create a client on three servers" or "drop one server from someone's subscription" are out of reach through them. This one speaks the current API.

The rest of the panel is covered too. 3x-ui serves its own OpenAPI document at /panel/api/openapi.json, and search_api / describe_api / call_api read it at runtime — so nodes, routing, backups and Xray control are reachable without a dedicated wrapper, and nothing here goes stale when the panel is upgraded.

Setup

Create a token in the panel under Settings → Security → API Token. It is shown once and stored only as a hash, so copy it right away.

Tools

Clients — list_clients, get_client, create_client, update_client, delete_client, attach_clients, detach_clients, reset_client_traffic, list_online_clients, list_client_groups, get_subscription_url

Inbounds and server — list_inbounds, get_inbound, server_status

Everything else — search_api, describe_api, call_api

Notes

• totalGB is in bytes and expiryTime is a Unix ms timestamp; 0 means unlimited and never.

• The panel answers 404 to a request with a missing, wrong or revoked token rather than 401. Errors from this server point that out, since the status alone reads like a bad path.

• Responses are wrapped as {success, msg, obj}. A success: false body is raised as a tool error carrying the panel's own message.

• With an admin-scoped token call_api can modify or delete inbounds, nodes and panel settings.
