Documentation Overview

oracle-feeds-mcp

An MCP server for on-chain price oracle data, covering two independent providers — Chainlink and Pyth Network — instead of one.

Why this exists

The only prior MCP server in this space, kukapay/chainlink-feeds-mcp, is Chainlink-only, hard-requires an Infura API key, has a queryPriceByRound tool that's a placeholder (it silently calls latestRoundData() again regardless of the round you asked for), and ships with no tests. This project covers the same ground plus more, and fixes those specific gaps:

	`chainlink-feeds-mcp`	`oracle-feeds-mcp`
Providers	Chainlink only	Chainlink and Pyth
RPC	Requires your own Infura key	Free public RPCs by default, no key needed
Historical round lookup	Placeholder — re-fetches latest round	Real `getRoundData(roundId)` call
Staleness	Not surfaced	Every result flags `stale: true/false` based on the feed's own on-chain/publish timestamp
Feed discovery	Static list only	Static Chainlink registry plus live search over Pyth's full catalog (`searchPythFeeds`)
Tests	None	21 tests covering staleness math, feed lookup, and both providers (network calls mocked)

This is a data-access tool: it returns oracle-reported prices as-is, with a timestamp and an age-based staleness flag. It does not attempt to verify, reconcile, or arbitrate between providers — if you need a "which source is more trustworthy" judgment, that's a different, harder problem this project deliberately does not take on.

Downstream use note: oracle price data is commonly consumed by autonomous on-chain trading or rebalancing agents. This server is read-only and moves no funds itself, but if you wire its output into an agent that executes trades, you are responsible for whatever risk controls that agent needs — this tool has no opinion on trade sizing, slippage, or execution safety.

Tools

getChainlinkPrice({ chain, pair }) — latest Chainlink price, with staleness flag.
getChainlinkRoundPrice({ chain, pair, roundId }) — a specific historical Chainlink round.
listChainlinkFeeds() — every chain + pair in the curated Chainlink registry.
listSupportedChains() — just the chain list.
getPythPrice({ symbol }) — latest Pyth price, by symbol (SOL/USD) or raw feed ID.
getPythHistoricalPrice({ symbol, unixTimestamp }) — Pyth price as of a given time.
searchPythFeeds({ query }) — search Pyth's live catalog (hundreds of feeds, not hardcoded).

Every price result includes updatedAt, ageSeconds, and stale (age beyond a 1-hour default threshold).

Coverage

Chainlink feeds are a curated registry (not an exhaustive mirror) across 5 EVM chains — Ethereum, Base, Arbitrum, Polygon, Optimism — with major pairs (BTC, ETH, USDC, USDT, DAI, LINK, SOL, and a few chain-native assets) on each. See src/feeds/chainlink.ts; it's a plain data file, easy to extend with more chains or pairs.

Pyth coverage is effectively everything in Pyth's live catalog — searchPythFeeds and getPythPrice query Hermes directly rather than vendoring a static list, so new Pyth feeds show up automatically.

Install & run

Terminal

npm install
npm run build
npm start

Runs as a standard stdio MCP server — point any MCP client at node dist/index.js.

No API keys or environment variables are required. Chainlink reads use free public RPC endpoints (*.publicnode.com); Pyth reads use its public Hermes REST API.

Development

Terminal

npm test        # 21 tests, network calls mocked
npm run typecheck
