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.

Transport: Streamable HTTP (remote, hosted — nothing to install or run)
Endpoint: https://api.sprytools.com/mcp
Auth: free API key via x-api-key header (or Authorization: Bearer)
Website: https://sprytools.com · API hub: https://sprytools.com/apis
Registry: com.sprytools/sprytools (official MCP Registry)

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"}}}'

Tools

Tool	Description	Parameters
`hash_text`	Compute a cryptographic hash (md5, sha1, sha256, sha512) of a text.	`text`, `algorithm` (default `sha256`)
`text_stats`	Analyze text: word/sentence counts, reading time and Flesch readability scores.	`text`
`validate_iban`	Validate an IBAN (ISO 13616 MOD-97) and return bank/country details.	`iban`
`validate_email`	Validate an email address: RFC syntax, MX records, disposable/role-based detection.	`email`
`dns_lookup`	Look up DNS records (A, AAAA, MX, TXT, NS, CNAME, SOA) for a domain.	`domain`, `type` (default `A`)
`convert_currency`	Convert an amount between currencies using current ECB exchange rates.	`from`, `to`, `amount`
`world_time`	Get the current time and UTC offset for an IANA timezone.	`timezone` (default `UTC`)
`check_domain`	Check whether a domain name is available for registration (WHOIS + DNS).	`domain`
`geo_audit`	Run a CiteReady GEO audit: how well AI search engines (ChatGPT, Perplexity, Google AI Overviews) can crawl, understand and cite a website. Returns score, grade and actionable findings.	`url`, `pages` (1–3, default `1`)

The SpryTools API hub exposes 30+ utility APIs in total; this MCP server surfaces the 9 most agent-relevant of them as tools. See https://sprytools.com/apis for the full catalog.

Notes

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.
