Overview

localcan mcp runs a Model Context Protocol server over stdio. An MCP host (Claude Code, Codex, Cursor, Claude Desktop, and others) launches it and calls LocalCan's tools to read captured traffic, manage Public URLs (tunnels), and publish Snapshots. LocalCan must be running for the tools to return data, so open the desktop app or run localcan start -d first. The server exposes twenty tools. Reading works out of the box. The eleven tools that change things need write access, which is off by default (see the switches below). Creating or adding a Public URL needs an active license. Publishing a Snapshot and password-protecting a URL need a subscription plan, so a perpetual license is turned away even though it can still open Public URLs. Unlicensed, the gated tools return a clear activation message, while pausing, resuming, and removing existing URLs still work.

Installation

claude mcp add --scope user localcan -- localcan mcp

Configuration

{
  "mcpServers": {
    "localcan": {
      "command": "/Users/you/.localcan/bin/localcan",
      "args": ["mcp"]
    }
  }

Capabilities

  • Inspect captured traffic

    Ask your assistant to list recent HTTP exchanges with `list_traffic` and view details of any exchange via `get_exchange`.

  • Create and manage Public URLs

    Have your assistant create a tunnel with `create_public_url`, list existing ones with `list_public_urls`, and pause or resume them.

  • Publish offline Snapshots

    Ask your assistant to publish a folder as a Snapshot with `publish_snapshot` so a link stays reachable when your machine is offline.

  • Protect URLs with passwords

    Have your assistant password-protect a Public URL with `set_password` and check protection via `get_access_status`.

  • Check capture status

    Ask your assistant to verify whether capture is on and how much traffic is buffered with `get_status`.
