Treasury Yields Skill

The tool

Give your agent the US Treasury curve. Call it as an MCP tool to read constant-maturity yields from 1-month to 30-year, plus TIPS.

Once your client is connected to the VerveKit MCP server, this appears in its tool list as TreasuryYieldsSkill. It is read-only and open-world: it fetches, it never mutates anything on your side, so most clients will call it without asking you to confirm.

{
  "name": "TreasuryYieldsSkill",
  "arguments": {}
}

Connecting

One server URL covers every skill in the catalog, including this one. Authorization is OAuth — the client opens a browser once and there is no key to paste into a config file.

{
  "mcpServers": {
    "vervekit": {
      "url": "https://api.vervekit.com/v1/mcp"
    }
  }

Per-client setup — Claude Desktop, Cursor, VS Code, ChatGPT — is on the MCP setup page.

Arguments

These are the properties on the tool's inputSchema, so a well-behaved client validates them before the call is made.

What the model gets back

The result carries a structuredContent object matching the tool's declared outputSchema, so a client can read fields without parsing prose. status is "ok" on success and error is null; a null field means the value wasn't available for that input, not that the call failed.

Fields

Failure modes

Errors come back as tool errors with a sentence the model can act on, not a bare status code.
