Live, current data for the Vercel AI SDK.

The Vercel AI SDK can attach MCP tools to any model call. Point it at one keyless URL and your agent gets 87 tools of fresh, current data the model was never trained on.

The call

Every tool is reachable over the keyless MCP endpoint, and also directly over REST. Here is the same data your AI SDK agent gets, called straight from a shell so you can see the signed, provenance-stamped envelope:

curl -s -X POST https://dynamicfeed.ai/v1/batch \
  -H 'Content-Type: application/json' \
  -d '{"calls":[
    {"tool":"reality_check","args":{"claim":"the latest stable Python is 3.12"}},
    {"tool":"software_version","args":{"product":"python"}}
  ]}'

Sample response

// Vercel AI SDK - attach Dynamic Feed as an MCP tool source
import { experimental_createMCPClient, generateText } from 'ai';
import { openai } from '@ai-sdk/openai';

const mcp = await experimental_createMCPClient({
  transport: { type: 'http', url: 'https://dynamicfeed.ai/mcp' }, // keyless
});

const tools = await mcp.tools();

const { text } = await generateText({
  model: openai('gpt-4o'),
  tools,
  prompt: 'Is my claim that the latest stable Python is 3.12 still correct?',
});

Why live data

The Vercel AI SDK exposes MCP tools to a model at call time, so the model can fetch a fact during a generateText or streamText run instead of guessing from training data. Dynamic Feed is a keyless MCP server built for exactly that: one URL, 87 tools across 19 verticals drawn from 70 sources, every datapoint stamped with its source, an observed-at timestamp, and a freshness state. Each response is also Ed25519-signed. Be precise about what the signature means: it is proof-of-existence and tamper-evidence - it proves Dynamic Feed reported this exact value at this exact time and that the bytes were not altered in transit. It is not a claim that the value is true, accurate, or safe to act on. Your agent still reasons over the data; the envelope just makes the data citeable and verifiable. Note the macro and rates feeds (interest_rates, treasury_yields, global_macro, china_data) are live economic data, not market prices - there is no live crypto, metal, or stock price conversion.

Use it for

• Attach live tools to a generateText or streamText call with one MCP client
• Let an AI SDK agent verify a claim against a current source before answering
• Add CVE, service-status, or weather awareness to a Next.js AI route handler
• Cite every tool result with a source, timestamp, and Ed25519 signature
