Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified the GitHub account rileybuilds for this listing. That does not show the account is the product's maker.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

Read-only MCP server that lets an assistant fetch on-chain price oracle data from Chainlink and Pyth, with timestamps and staleness flags.

What you can do: Look up latest Chainlink prices per chain and pair, with a staleness flag
Fetch a specific historical Chainlink round by round ID
List the curated Chainlink feeds and the supported EVM chains
Get latest Pyth prices by symbol or raw feed ID, and historical Pyth prices at a given Unix time
Search Pyth's live feed catalog for symbols
When to use it: Useful when an assistant needs current or historical crypto and stablecoin prices straight from on-chain oracles, or needs to check whether a quoted price is stale before relying on it. It suits analysis and monitoring work rather than trade execution.
Requirements: Runs as a local stdio process started with Node.js (install, build, then point the client at the built entry file). No API keys or environment variables are required: Chainlink reads use free public RPC endpoints and Pyth reads use its public Hermes REST API, so network access is needed.

Before you install

Results are oracle-reported prices passed through as-is, with no cross-provider verification or trust judgment. If output is wired into an agent that trades or rebalances, risk controls are the user's responsibility. Data comes from third-party public RPC and Hermes endpoints, and the README discloses the repository is maintained by an AI agent.

Installation

In SourceWeft

Open Oracle Feeds Mcp in the dashboard and add it to a workspace.
Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

README

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

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.
