One API key, from your dashboard, authenticates both the REST API and the MCP server.

Guide

Treasury indices

The eleven total-return indices: what each covers, how to read levels, returns and analytics, and the two date conventions.

REST

The full reference is generated from the API itself: https://api-staging.saferate.markets/reference.

curl https://api-staging.saferate.markets/v1/curves/zero \
  -H "Authorization: Bearer $SAFERATE_MARKETS_KEY"

MCP

For AI assistants and agents. Streamable HTTP at https://api-staging.saferate.markets/mcp, authenticated with the same key as a Bearer header.

Claude Code

claude mcp add --transport http saferate-markets https://api-staging.saferate.markets/mcp \
  --header "Authorization: Bearer $SAFERATE_MARKETS_KEY"

Any client that reads an mcpServers file

{
  "mcpServers": {
    "saferate-markets": {
      "type": "http",
      "url": "https://api-staging.saferate.markets/mcp",
      "headers": { "Authorization": "Bearer ${SAFERATE_MARKETS_KEY}" }
    }
  }
}

Keep the key in an environment variable rather than in the file. Sign-in based connection for claude.ai and Claude Desktop is not available yet.
