SpryTools MCP Server

A hosted Model Context Protocol server that gives AI agents 9 ready-to-use utility tools — hashing, text stats, IBAN & email validation, DNS lookup, currency conversion, world time, domain availability, and CiteReady GEO audits.

Discovery without a key: the server card and the initialize / tools/list handshake are public, so registry crawlers and MCP hosts can introspect the server. tools/call requires a key and counts against your plan quota.

Quickstart

1. Get a free key
curl -X POST https://api.sprytools.com/v1/signup \
  -H "content-type: application/json" \
  -d '{"email":"you@example.com"}'
2. Add the server to your MCP client

Most clients that support remote / streamable-HTTP MCP servers take a config block like this:

{
  "mcpServers": {
    "sprytools": {
      "type": "streamable-http",
      "url": "https://api.sprytools.com/mcp",
      "headers": { "x-api-key": "YOUR_KEY" }
    }
  }
}

For clients that only speak stdio, bridge via mcp-remote:

{
  "mcpServers": {
    "sprytools": {
      "command": "npx",
      "args": ["mcp-remote", "https://api.sprytools.com/mcp", "--header", "x-api-key:YOUR_KEY"]
    }
  }
}
3. Call a tool (raw JSON-RPC)
curl -X POST https://api.sprytools.com/mcp \
  -H "content-type: application/json" \
  -H "accept: application/json, text/event-stream" \
  -H "x-api-key: YOUR_KEY" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"validate_iban","arguments":{"iban":"DE89370400440532013000"}}}'

The canonical source for the tool list is the live server card at https://api.sprytools.com/.well-known/mcp/server-card.json. This repository holds the public MCP manifest (server.json) and documentation only — no server code or secrets. The server itself is operated as a hosted service.
