signal8ai/signal8-mcp

MCP (Model Context Protocol) server for Signal8 -- AI-extracted SEC filing intelligence data.
Gives AI agents like Claude, Cursor, and other MCP-compatible tools direct access to:
- **Company fundamentals** (quotes, financials, earnings, float, executives, peers, news)
- **Dilution analysis** (warrants, convertibles, preferred, shelf registrations, ATMs, equity lines and S-1 offerings, each figure cited to the SEC filing it was read from)
- **Dilution Pressure Score** (0-100, seven components: shelf capacity, ATM/equity-line capacity, warrants in the money, convertible proximity, cash burn, historical dilution, toxic financing)
- **Baby shelf capacity** (S-3 General Instruction I.B.6 one-third-of-float cap, recomputed from the live float)
- **Cash runway** (cash position, monthly burn, capital raises since the last balance sheet)
- **Intelligence** (counterparties, counsel, insiders, institutions, ROFR triggers, cluster buys)
- **Cross-company intelligence** (top AUM institutions, cross-company counsel & insider patterns)
- **Compliance monitoring** (Nasdaq/NYSE deficiency detection, listing classification)
- **Company screening** (dilution-aware filters with 30+ fields)
- **ETF analysis** (holdings, sectors, countries, performance, comparables)
Installation
Setup
1. Get your API key
API and MCP access are included with **Signal8 Pro** ($59/mo, or $588/yr). A free Signal8 account cannot create API keys. Upgrade at signal8.ai/pro, then create a key in the developer portal at signal8.ai/developer/api-keys.
Using Claude.ai or Claude Desktop? You can skip the key entirely: add the hosted server as a custom connector and sign in with your Signal8 account (see Hosted Endpoint).
2. Configure your MCP client
Claude Desktop
Add to your Claude Desktop config file:
**macOS:** ~/Library/Application Support/Claude/claude_desktop_config.json
**Windows:** %APPDATA%\Claude\claude_desktop_config.json
