Pyth Pro MCP Server
MCP server that gives AI assistants access to real-time and historical market data from Pyth — 500+ price feeds across crypto, equities, FX, commodities, and more.
Hosted at https://mcp.pyth.network/mcp
Quick Start
Each snippet sends your own Pyth Pro API key as an Authorization: Bearer header, so you set it once (see Access Token).
Claude Code
This adds Pyth only to the folder you run the command in. To use it in every project, add --scope user; any project you open can then call the price tools with your key.
Claude Desktop
Claude Desktop connects to remote servers as custom connectors, which can send your key as a header only where Anthropic's request-headers beta is enabled. To set the key once on any plan, bridge with mcp-remote (needs Node.js) in claude_desktop_config.json (Claude menu bar → Settings… → Developer → Edit Config):
mcp-remote is a community package, not maintained by Pyth, and it handles your key; the snippet pins the version we tested.
Or add https://mcp.pyth.network/mcp as a custom connector: on Free, Pro or Max under Customize → Connectors → Add custom connector; on Team or Enterprise an Owner adds it under Organization settings → Connectors → Add → Custom, and members click Connect under Customize → Connectors. With the request-headers beta, choose No sign-in and add an authorization header Bearer YOUR_TOKEN (on Team and Enterprise plans the Owner sets it for the whole organization, so everyone shares that key); otherwise pass the key per call.
Cursor
Add to ~/.cursor/mcp.json (global, so the key stays out of your repo):
To keep the key out of the file, write "Bearer ${env:PYTH_PRO_ACCESS_TOKEN}" and set that variable in your shell profile or system environment.
VS Code
Add to ~/.copilot/mcp-config.json, a user-level file that VS Code's chat and its Agent Host sessions both read. It holds your key in plain text, so never copy it into a repository. (VS Code's ${input:...} prompt avoids that, but Agent Host sessions do not receive .vscode/mcp.json servers that use it.)
Other Clients
Any MCP client that supports Streamable HTTP: connect to https://mcp.pyth.network/mcp with the header Authorization: Bearer YOUR_TOKEN.
Tools
Tip: Use get_symbols first to discover available feeds. Price tools accept full symbols (Crypto.BTC/USD) or bare pairs (BTC/USD). A bare pair resolves to the live spot feed when there is one, otherwise to the only remaining match (e.g. BTC/USDT → the Binance funding-rate feed); if several remain, the error lists them.
Access Token
Every user brings their own Pyth Pro access token. It is required for get_latest_price, get_historical_price, get_price_range and get_candlestick_data. get_symbols works without one, but with a token it also lists feeds visible only to Pro keys and marks each feed entitled: true/false (whether your token can query it right now). convert_date_to_timestamp never needs one.
- Get a token: Acquire an API key
- Give the server your token in one of three ways. A token passed on a call wins over a configured one.
- Configure it once for the hosted server: send it as an
Authorization: Bearer header from your MCP client (see Quick Start), so your assistant does not handle it on every call.
- Configure it once for a local stdio server: set
PYTH_PRO_ACCESS_TOKEN in the server's env block in your client config (see Local stdio config).
- Per call: the
access_token tool parameter. Your assistant asks for it when no token is configured. Clients that cannot send headers (e.g. Claude Desktop custom connectors without the request-headers beta) use this.
- The server never has a key of its own: the hosted server ignores
PYTH_PRO_ACCESS_TOKEN in its own environment and only uses the key each user sends.
- A 401 means the token is invalid or expired. A 403 means the token is valid but your plan is not entitled to that feed; the error names the entitlement group required.
- Only feeds in state
stable return prices. Requested feeds that come back without a price (e.g. beta or coming_soon feeds, or a channel faster than the feed's min_channel) are listed in missing_feed_ids.
Example Queries
Try these with any connected AI assistant:
- "What's the current price of Bitcoin?"
- "Show me the ETH/USD price history for the last 24 hours"
- "Compare the prices of gold and silver right now"
- "Get daily candlestick data for AAPL over the past week"
- "What crypto price feeds are available on Pyth?"
- "Show every BTC/USD price update in the 30 seconds after 14:30 UTC today"
- "Which VIX futures contracts does Pyth have?"
