Live data for the OpenAI Agents SDK.
Your OpenAI Agents SDK agent only knows what was in its training cut-off. Point its MCP integration at one keyless URL and it gets 94 tools of fresh, current data, each datapoint signed and stamped with source and observed-at time.
The call
No key needed. Try the same tools your agent will call, straight from a terminal. Each result comes back with an Ed25519 signature and a provenance block (source, observed-at, freshness):
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
{ "mcpServers": { "dynamic-feed": { "url": "https://dynamicfeed.ai/mcp" } } }Why live data
The OpenAI Agents SDK can attach MCP servers as tools the model calls at runtime. The problem is the model's knowledge stops at its training cut-off, so it guesses at anything current - today's CVEs, whether a service is down, the latest package version, live macro and rates figures. Dynamic Feed is the keyless MCP server that fills that gap: register one URL and the agent gets 94 live tools across 20 domains drawn from 78 sources. Every datapoint is Ed25519-signed and carries provenance: source, observed-at time, and freshness. The signature establishes integrity and attribution under the published key, so altered bytes fail verification; it does not independently prove time, truth, accuracy, or safety. Your agent still decides how to use the fact; we make the record verifiable and traceable to its origin. Note there is no live crypto, metal, or stock price conversion here - the finance tools are macro and rates (interest_rates, treasury_yields, global_macro, china_data), not market prices.
Use it for
- Stop an Agents SDK agent answering current questions from a stale training cut-off
- Ground a tool call in a citeable, signed fact with a source URL and timestamp
- Give an agent live awareness of CVEs, service outages, software versions and weather hazards
- Hand the agent verifiable data it can pass through to an audit log or downstream check
FAQ
How do I add this to the OpenAI Agents SDK?
Register Dynamic Feed as an MCP server. The endpoint is https://dynamicfeed.ai/mcp over Streamable HTTP, keyless. Use the SDK's hosted MCP tool or a Streamable HTTP MCP server pointed at that URL, and the 94 tools appear to your agent automatically. Prefer plain HTTP? POST a batch of tool calls to https://dynamicfeed.ai/v1/batch, also keyless.
Do I need an API key?
No. Both the MCP endpoint and POST /v1/batch are keyless and free for fair use. There is nothing to sign up for to try it.
What does the Ed25519 signature actually prove?
It establishes integrity and attribution under the published key, so altered bytes fail verification. It does not independently prove time, truth, accuracy, or safety. Your agent still decides how to act on the fact.
