Which integrations are available for this server?

Supports deployment as a self-hosted MCP server on Cloudflare Workers runtime, enabling financial data tools to run on edge infrastructure.

Toolstem MCP Server

Agent-ready financial intelligence tools — curated, not raw.

Toolstem is an MCP (Model Context Protocol) server that turns raw financial market data into curated, synthesized intelligence for AI agents. Unlike passthrough wrappers that just expose a vendor's REST API, every Toolstem tool combines multiple data sources, derives signals, and pre-computes the math an agent would otherwise have to do itself.

One call. One agent-friendly JSON response. No nested arrays to parse, no cross-endpoint stitching, no null-checking boilerplate.

Why Toolstem?

Most financial MCP servers expose one tool per API endpoint — forcing your agent to make 4–5 sequential calls, write glue code, and reason about raw data shapes. Toolstem is built differently:

Parallel data fetching — every tool fans out to multiple sources concurrently.
Derived signals — human-readable recommendations like UNDERVALUED, STRONG, ACCELERATING computed from raw numbers.
Pre-computed math — CAGRs, YoY growth, margin trends, distance from 52-week high/low, FCF yield, and more are already in the response.
Flat, predictable schema — no deeply nested vendor quirks leaking into agent prompts.
Graceful degradation — if one upstream endpoint fails, the rest of the response still comes through with nulls in place.

Tools

Smithery

Toolstem is distributed on Smithery for one-click installation into supported MCP clients.

Apify

Available on the Apify Store as the toolstem-financial-data Actor. Call it from your Apify workflow with input:

{
  "tool": "get_stock_snapshot",
  "symbol": "AAPL"
}

{
  "tool": "get_company_metrics",
  "symbol": "AAPL",
  "period": "annual"
}

Results are pushed to the default dataset. The actor monetizes per tool call via Apify's Pay-Per-Event model.

Self-hosting (Cloudflare Workers / any Node runtime)

Build and run the HTTP transport:

npm install
npm run build
FMP_API_KEY=your_key npm run start:http

Your MCP client can then connect to POST http://your-host:3000/mcp.

Environment Variables

Variable	Required	Description
`FMP_API_KEY`	Yes	Financial Modeling Prep API key. Get one at financialmodelingprep.com.
`PORT`	No	Port for HTTP transport. Defaults to `3000`.

npm install
npm run dev           # stdio, hot reload via tsx
npm run build         # TypeScript -> dist/
npm start             # run built stdio server
