Pyth Pro MCP sunucusu

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

claude mcp add --transport http pyth https://mcp.pyth.network/mcp --header "Authorization: Bearer YOUR_TOKEN"

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):

{
  "mcpServers": {
    "pyth": {
      "command": "npx",
      "args": ["-y", "mcp-remote@0.14.3", "https://mcp.pyth.network/mcp", "--header", "Authorization:${PYTH_AUTH_HEADER}"],
      "env": { "PYTH_AUTH_HEADER": "Bearer YOUR_TOKEN" }
    }
  }
}

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):

{
  "mcpServers": {
    "pyth": {
      "url": "https://mcp.pyth.network/mcp",
      "headers": { "Authorization": "Bearer YOUR_TOKEN" }
    }
  }
}

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.)

{
  "mcpServers": {
    "pyth": {
      "type": "http",
      "url": "https://mcp.pyth.network/mcp",
      "headers": { "Authorization": "Bearer YOUR_TOKEN" },
      "tools": ["*"]
    }
  }
}

Other Clients

Any MCP client that supports Streamable HTTP: connect to https://mcp.pyth.network/mcp with the header Authorization: Bearer YOUR_TOKEN.

Tools

Tool	Description	Auth Required
get_symbols	Search and list price feeds; filter by asset type, instrument type or futures chain	Optional (adds Pro-only feeds and an entitled flag per feed)
get_latest_price	Real-time prices for one or more feeds	Yes (access token)
get_historical_price	Point-in-time price snapshots	Yes (access token)
get_price_range	Every price update within a window of up to 60 seconds	Yes (access token)
get_candlestick_data	OHLC candlestick bars for charting and analysis	Yes (access token)
convert_date_to_timestamp	Convert date strings to Unix timestamps	No

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?"

Local Development

For contributors working on the MCP server itself.

Build

pnpm --filter @pythnetwork/mcp build

MCP Inspector

Run the inspector to interactively test tools:

npx @modelcontextprotocol/inspector --cli -- pnpm --filter @pythnetwork/mcp start:stdio:dev

Local stdio config

To connect a client to a local build via stdio:

{
  "mcpServers": {
    "pyth-mcp": {
      "command": "node",
      "args": ["<path-to-repo>/apps/mcp/dist/index.js"],
      "env": { "PYTH_PRO_ACCESS_TOKEN": "YOUR_TOKEN" }
    }
  }
}

Environment Variables

Variable	Default	Description
