CEV-OS Data API MCP

An official MCP server provided by Cutting Edge Ventures that exposes their free US macro, market sentiment, and event data API. It allows AI agents to retrieve market mood gauges, stock sentiment, macro release calendars, catalyst events, release statuses, macro regimes, incident assets, and earnings reaction statistics via specific tools like get_market_mood and get_macro_calendar.

Endpoint and access

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.

Claude Code configuration

claude mcp add --transport http cev-os-data-api-mcp https://mcp.cev-os.com/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).

Codex configuration

codex mcp add cev-os-data-api-mcp --url https://mcp.cev-os.com/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable cev-os-data-api-mcp in your MCP settings.

Cursor configuration

{
  "mcpServers": {
    "cev-os-data-api-mcp": {
      "url": "https://mcp.cev-os.com/mcp"
