MCP install | 514 Docs

To add the hosted MCP and an optional feedback prompt together, install the AX plugin.

Use the install instructions for your agent host:

Install Fiveonefour's MCP server directly in Cursor. If Cursor opens MCP settings without an install prompt, add this same server config manually.

{
  "mcpServers": {
    "Fiveonefour": {
      "url": "https://app.514.ax/mcp"
    }
  }
}

After connecting, follow the sign-in prompt from your MCP host, then verify Fiveonefour tools appear in your agent session. See the tool catalog for what your agent can do with them.

Tool list

The server lists only a few tools: learn, a handful of small reads, and two that reach every other tool. That keeps the list to a few kilobytes of your agent's context window instead of every tool's schema.

Tool	What it does
`tool_search`	Find tools by words (`query`) or by exact `name`. Each match carries its description, whether it reads or changes data, its input schema, and a `reference`. Pages with `limit` and `cursor`.
`tool_execute`	Run a found tool: pass its `name` and `arguments`, and optionally its `reference` so the call is refused if the tool changed since. The arguments are checked against the tool's schema before it runs.

Your agent finds a tool with tool_search, for example {"query": "report create"}, then runs it with tool_execute and {"name": "report_create", "arguments": {...}}. The result is the tool's own result.

Every tool stays available, with the same permissions, and a tool you already know by name can still be called directly. Your host's per-tool approval prompts apply to tool_execute as a whole rather than to each tool it runs.

List every tool

To list every tool instead, for example to approve or allowlist tools one by one, add ?catalog=full to the server URL:

claude mcp add --transport http ax "https://app.514.ax/mcp?catalog=full"

The full list takes a large share of an agent's context window before its first call. ?catalog=search is also accepted and serves the default list.
