Option Chain MCP server
Option Chain MCP server. That is what the options mcp server brings to an AI assistant: the same capability, reachable through the Model Context Protocol rather than a separate app or dashboard.
This Model Context Protocol (MCP) server gives AI assistants the tools to research options, without any ability to place trades:
The server publishes 9 tools. What each one is for:
Read — only by design.** No place_order, no close_position, no exercise_options_position. Point an LLM at it without worrying about hallucinated tradesProvider — pluggable.** Tradier and Alpaca behind one identical tool surface. Swap with one env var; if one provider's data goes stale or the account expiresmacOS — ~/Library/Application Support/Claude/claude_desktop_config.jsonWindows — %APPDATA%\Claude\claude_desktop_config.jsonAlpaca — ALPACA_API_KEY_ID, ALPACA_SECRET_KEYField — Tradieropen_interest — Returned nativelyRequirements — The Requirements tool exposed by this serverDeploy — The Deploy tool exposed by this serverInstallation goes through your MCP client rather than a global install: point it at wrangler on npm and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.
Configuration is passed through the environment: TRADIER_TOKEN, ALPACA_API_KEY_ID, ALPACA_SECRET_KEY. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
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)Plenty of cloud and infrastructure servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Options's toolset — Read, Provider, macOS and 6 more — is a fair guide to whether it matches your workflow. It is maintained by blake365; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
| Tool | What it does |
|---|---|
| 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. |
