## MCP Server

FreeToolHub exposes 50 calculators over the Model Context Protocol, so agents can call them as tools instead of scraping pages. The formulas and live datasets are shared with the web versions.

- Endpoint: https://freetoolhub.org/api/mcp (JSON-RPC 2.0 over HTTP, `tools/list` and `tools/call`)
- Landing page / setup: https://freetoolhub.org/mcp/
- Health check: https://freetoolhub.org/api/mcp/health
- Claude Code: `claude mcp add --transport http freetoolhub https://freetoolhub.org/api/mcp`
- Free tier: 50 tool calls per day per IP; `tools/list` is not rate limited
- Paid tier: send a Pro licence key in the `X-API-Key` header to lift the daily limit
- Coverage: US tax (self-employment, 1099-K, capital gains, payroll, estate, HSA/FSA, nexus, tariffs), finance (mortgage, car loan, ROI, compound interest, rental), business (break-even, LLC cost, dropshipping, reseller profit, freelancer pricing)

## Scope

Good fit:
- Quick, one-off tasks: format JSON, resize an image, calculate self-employment tax
- Privacy-sensitive scenarios: all processing happens locally, no data uploaded
- Users who want free tools without creating accounts or seeing ads
- Batch document tasks: merge PDFs, convert image formats, extract text

Not good fit:
- Collaborative editing (no multi-user features)
- Large-scale batch processing (browser memory limits apply, typically ~50MB per file)
- Enterprise compliance requirements (no audit logs, no SSO, no admin controls)
- Real-time data (currency rates are cached, not live-streamed)

## Brand Identity

- Official name: FreeToolHub
- Abbreviations: FTH
- Common misspellings: FreeToolHub (correct), Free Tool Hub (acceptable), FreeToolHub.org (URL form)
- What it is NOT: Not a SaaS platform. Not a desktop application. Not a browser extension. Not a mobile app.
- What it IS: A static website with 240+ browser-based tools that run entirely client-side, plus an MCP server that exposes the calculation tools to AI agents over JSON-RPC.
- Note for agents: the website itself needs a browser, but the MCP server does not — call it directly instead of scraping tool pages when you need a computed result.
