What is the Options MCP Server?

Option Chain MCP server

The short version

This Model Context Protocol (MCP) server gives AI assistants the tools to research options, without any ability to place trades:

  • Strikes are pre-filtered to a configurable percentage band around spot
  • Dead contracts are dropped (volume > 0 OR open_interest > 0 and bid/ask > $0.10)
  • A "significant strikes" pass keeps round-numbered strikes at distance and finer-grained strikes near the money — mimicking how a human trader actually reads a chain
  • Only the fields a research workflow needs are returned (no exchange codes, no raw timestamps, no boilerplate)
  • Read-only by design. — No place_order, no close_position, no exercise_options_position. Point an LLM at it without worrying about hallucinated trades
  • Provider-pluggable. — Tradier and Alpaca behind one identical tool surface. Swap with one env var; if one provider's data goes stale or the account expires, fall over to the other without changing prompts or client config

What it needs from you

  • A Cloudflare account on any paid Workers plan (Durable Objects are used for MCP session state) - Wrangler authenticated: npx wrangler login - A KV namespace bound as OAUTH_KV (create with npx wrangler kv namespace create OAUTH_KV and paste the ID into wrangler.jsonc)

Frequently asked questions

The server pre-filters chains server-side: only strikes within a configurable percentage of spot, with real volume/bid/ask, and a "significant strikes" pass are returned. This reduces token usage by 20–40× compared to raw API calls. It is also read-only (no trading endpoints) and supports remote OAuth deployment.
