LAB 02 — MODEL CONTEXT PROTOCOL SERVER

Signal Line

A live MCP server exposing this dataset's tools and data directly to Claude and other MCP clients — the same dataset The Listening Post reads from, wired up for an AI assistant to query and act on directly.

01
WHAT IS MCP

Tools an AI assistant can actually use

The Model Context Protocol (MCP) is an open standard that lets an AI assistant like Claude call an application's own tools and read its data directly, instead of a human copy-pasting context back and forth. Signal Line is a real MCP server — every tool and resource below is live and callable right now.

Claude Desktop's built-in Custom Connector UI only supports OAuth Client ID/Secret, not a static bearer token — so this server connects through the mcp-remote stdio bridge instead.


Add the config above in (Settings → Developer → Edit Config), save, and restart Claude Desktop.

Get a demo token

This is a live demo, not a public endpoint — get in touch for a read-only demo token.

Access today is gated by a shared bearer-token header, checked against an environment secret — a demo-grade shortcut, not a production auth model. The demo token is read-only: it can query tools freely but any write (like flagging an account) is politely refused. A real deployment would sit behind Doorkeeper/OAuth 2.1, issuing scoped, revocable tokens per client instead of one shared secret per role.
