Why olywork.com

Why call Polygon.io through olywork.com

Your account, held safely

Connect once; olywork.com keeps the credential server-side and injects it per call. No key on any machine.

Price before the call

The provider's own rate, $0.000 markup. How billing works.

Account billing

Calls through your own connection are not metered by olywork.

Your own Polygon.io key is free

Register it and those calls are never metered. Your key always wins.

Switch by changing a word

Another provider is a different word in the prompt, not a new integration.

One key, the whole catalog

The same token calls EODHD, Financial Datasets, Finnhub and 3,273 other tools.

Questions

Before you start

Do I need a Polygon.io account?

Yes. This is an own-account connection: you sign in to Polygon.io once and your agent uses that connection through your olywork.com token. Calls on it are never metered.

How do I add Polygon.io to Claude Code?

Run: claude mcp add --transport http olywork https://olywork.com/mcp. One MCP server carries Polygon.io and the rest of the catalog.

Which frameworks does it work with?

Anything that speaks MCP (Claude Code, Claude Desktop, ChatGPT, Codex, Cursor, Grok) and anything that can make an HTTP request (LangChain, CrewAI, LlamaIndex, plain code).

Is this the official Polygon.io MCP server?

No. olywork.com serves Polygon.io's real API through its own metered proxy: the request is the provider's own, the credential is injected server-side, and the answer is relayed verbatim. The official Polygon.io channels are linked above.
