name: LINE Bot MCP Server
description: >-
  First-party Model Context Protocol server published by LY Corporation that
  wraps the LINE Messaging API so an AI agent can drive a LINE Official
  Account — pushing and broadcasting text and Flex messages, reading a user
  profile, checking the monthly message quota, and managing rich menus. LINE
  labels the repository a preview version and notes it may not include complete
  functionality or comprehensive support.
vendor: LY Corporation (LINE)
license: Apache-2.0
deployment:
  mode: local-stdio
  install: npx @line/line-bot-mcp-server
  package: https://www.npmjs.com/package/@line/line-bot-mcp-server
  auth: api-key
  verified: searched
  note: >-
    There is no hosted/remote MCP endpoint. LINE ships only a locally-run stdio
    server: a human installs it (npx, or the published Docker image
    line/line-bot-mcp-server run with `docker run -i --rm`) and supplies
    CHANNEL_ACCESS_TOKEN and DESTINATION_USER_ID as environment variables. An
    agent cannot reach LINE over MCP without that local install step. The
    "api-key" auth mode is a LINE channel access token, not an OAuth flow.

  note: >-
    Tool names and descriptions are transcribed from the first-party README at
    github.com/line/line-bot-mcp-server. Because the server is stdio-only there
    is no endpoint to POST tools/list against, so full JSON Schema inputSchema
    bodies were not introspected; the inputs listed are the README's documented
    parameters. See mcp/line-tool-crosswalk.yml for the binding of each tool to
    the backing Messaging API operationId.
