Agent Gateway · Model Context Protocol

Ask Kitalpha for its data from inside your AI assistant.

One URL. Any MCP client. Seven read-only tools over data Kitalpha already publishes — and every answer comes back in a signed envelope that states its licence terms and proves, with a published key, that it left Kitalpha unaltered.

Quickstart

The menu labels below are as they stood in August 2026; the one thing that does not change is the URL.

claude mcp add --transport http kitalpha https://api.dwkitalpha.com/mcp

curl -s https://api.dwkitalpha.com/mcp \
  -H 'content-type: application/json' \
  -H 'accept: application/json, text/event-stream' \
  -d '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2025-06-18","capabilities":{},"clientInfo":{"name":"me","version":"1"}}}'

curl -s https://api.dwkitalpha.com/mcp \
  -H 'content-type: application/json' \
  -H 'accept: application/json, text/event-stream' \
  -H 'mcp-protocol-version: 2025-06-18' \
  -d '{"jsonrpc":"2.0","id":2,"method":"tools/call","params":{"name":"get_gatewatch_universe","arguments":{}}}'

The tools (read live from the gateway just now)

Read-only by construction: nothing here writes, nothing here triggers the content engine, and nothing here reaches a data provider — every tool reads rows Kitalpha already stores. Gate Watch through this door is the free tier (the same record the public fund pages show); the complete accession-linked record is the Gate Watch Pro product and is not served here.

The signed envelope

Every response is { payload, provenance }. The payload is the answer. The provenance block carries the SHA-256 of the payload over RFC 8785 canonical JSON, the signing instant, the key id, one licence entry per dataset the answer drew on (its attribution line, resale flag and terms URL), the terms of the feed itself, and an Ed25519 signature over all of that. Alter the data, the timestamp or a licence line and the signature fails. The format is published as an open specification so anyone can implement or verify it: Kitalpha Provenance Envelope, version 1.

Verify it yourself

With nothing from Kitalpha but the published registry:

// Node 20+ (or any WebCrypto runtime). Verifies an envelope with nothing but the published registry.
const canon = (v) => v === null || typeof v !== "object" ? JSON.stringify(v)
  : Array.isArray(v) ? `[${v.map(canon).join(",")}]`
  : `{${Object.keys(v).filter((k) => v[k] !== undefined).sort().map((k) => `${JSON.stringify(k)}:${canon(v[k])}`).join(",")}}`;
const bytes = (h) => Uint8Array.from(h.match(/../g), (x) => parseInt(x, 16));
const hex = (b) => [...new Uint8Array(b)].map((x) => x.toString(16).padStart(2, "0")).join("");

const registry = await (await fetch("https://dwkitalpha.com/.well-known/kitalpha-provenance.json")).json();
const { payload, provenance } = envelope;                      // the { payload, provenance } you received
const key = registry.keys.find((k) => k.key_id === provenance.key_id);
const { signature, ...unsigned } = provenance;
const pub = await crypto.subtle.importKey("raw", bytes(key.public_key_hex), { name: "Ed25519" }, false, ["verify"]);
const sigOk = await crypto.subtle.verify({ name: "Ed25519" }, pub, bytes(signature), new TextEncoder().encode(canon(unsigned)));
const hashOk = hex(await crypto.subtle.digest("SHA-256", new TextEncoder().encode(canon(payload)))) === provenance.payload_hash;
console.log({ sigOk, hashOk });                                // both true ⇒ unaltered, and from Kitalpha

Or ask the gateway: the verify_receipt tool runs exactly this check and returns the verdict — in a signed envelope of its own.

Published keys

Registry: https://dwkitalpha.com/.well-known/kitalpha-provenance.json. A retired key is never removed; everything it signed inside its interval still verifies.

Licence terms

Free use with attribution to Kitalpha Finance (https://dwkitalpha.com) and to the originating source named in each licence entry. The gateway feed itself may not be resold, sublicensed or redistributed as a data product. General information only; nothing in any payload is financial advice.

The terms of the data travel with each answer, drawn from the same licence registries the website publishes under. The gate the gateway applies, stated in full:

• U.S. economic calendar — agency schedules (BLS, BEA, Census, the Federal Reserve, Treasury) are U.S. government works and are served. The impact tiers are withheld: they rest on FRED-derived release-date history and FRED's terms forbid use of its data with AI systems. No consensus estimates exist in the data at all.
• International calendar — a source is served only when its licence was verified by a human, resale is permitted, and there is no paid-tier permission hold. Sources with a pass-through clause are served with their terms. The withheld sources are listed, with the reason, in every answer.
• Macro series — the Treasury par, bill and real curves, the Treasury-derived spreads, and Henry Hub when read from the EIA directly. Every FRED-sourced series is withheld (and listed, with the reason): FRED's terms forbid AI/LLM use.
• Gate Watch — read from funds' own SEC EDGAR filings (U.S. government works). Quote figures as “according to Kitalpha Gate Watch data”. Free tier only.
• Signed Briefs — Kitalpha's own editorial content: quote with attribution and a link; no resale. Each brief's ledger receipt is included so the brief itself can be verified.

What this is not

It is not financial advice and it is not a recommendation engine: the tools describe what filings, schedules and statements say, and the answers draw no conclusion about any fund, market or security. It is not a private feed — everything served here is already public on this site. And it is not a guarantee that a payload is true; it is a guarantee that the payload is what Kitalpha produced, when, and under which terms. The truth claims are the source citations inside each payload — a filing URL, an agency schedule, a central-bank statement.
