EarningsCalls MCP Server

Website · MCP setup guide · API docs · License: MIT

Model Context Protocol server that gives AI agents direct access to the EarningsCalls.dev dataset — 177,000+ earnings call transcripts from 17,000+ companies across 70 countries and 170+ exchanges (2020 to present), with 11M+ speaker segments cleanly tagged by role (Executive / Analyst / Operator / Attendee / Shareholder), full-text search, and more.

Ask Claude (or any MCP-capable client) about any earnings call in natural language:

"What did NVIDIA's CFO say about data center growth in their last call?" "Compare Tesla's gross-margin commentary across the last four quarters." "Find S&P 500 companies that mentioned 'tariffs' in their Q2 2026 calls."

Built as a thin MCP wrapper around the public REST API at https://earningscalls.dev/api/v1. New calls land within minutes of the call ending.

Requirements

• A paid EarningsCalls subscription (Pro, Ultra, or Enterprise). The free test key does not work here — grab a plan at earningscalls.dev/#pricing (from $24.99/month).

• For the local method only: Node.js 18+.

Installation

Two remote options (zero install, recommended) and one local option.

Option A — Connector URL (recommended)

The easiest path: a personal connector URL with the token embedded, so there's no API-key header to manage.

1. Go to earningscalls.dev/dashboard → Connectors → Generate.

2. Copy the URL — it looks like https://earningscalls.dev/u/<your-token>/mcp.

Claude Desktop / claude.ai (web): Settings → Connectors → Add custom connector → paste the URL → Add. (On the web, leave the OAuth fields empty and confirm the consent popup.)

Claude Code (CLI):

claude mcp add --transport http earningscalls "https://earningscalls.dev/u/<your-token>/mcp"
# add --scope user to make it available in every project

Cursor — .cursor/mcp.json:

{
  "mcpServers": {
    "earningscalls": {
      "url": "https://earningscalls.dev/u/<your-token>/mcp"
    }
  }
}

Each connector URL is independently revocable — generate one per device or workspace.

Option B — API-key header

Point your client at the hosted endpoint and pass your API key (ect_...) via the X-API-Key header.

Claude Code (CLI):

claude mcp add earningscalls --transport http https://mcp.earningscalls.dev/mcp \
  --header "X-API-Key: ect_your_key_here"

Claude Desktop / Cursor — config:

{
  "mcpServers": {
    "earningscalls": {
      "url": "https://mcp.earningscalls.dev/mcp",
      "headers": { "X-API-Key": "ect_your_key_here" }
    }
  }
}

Option C — Local (via npx)

Runs the server as a local process over stdio.

claude mcp add earningscalls \
  --env EARNINGSCALLS_API_KEY=ect_your_key_here \
  -- npx -y @earningscalls/mcp-server

Or in a client config:

{
  "mcpServers": {
    "earningscalls": {
      "command": "npx",
      "args": ["-y", "@earningscalls/mcp-server"],
      "env": { "EARNINGSCALLS_API_KEY": "ect_your_key_here" }
    }
  }
}
