For agent builders

Florida tax-certificate data for your agent stack, in 60 seconds

Building on Claude Code, OpenClaw, Hermes, or rolling your own MCP-compliant agent? Drop this MCP endpoint into your config. Florida tax certificate + delinquency tools: ranked certificate search over 1,267,795 records, certificate detail, by-parcel lookup, grouped counts, certificate-sale summaries, and the 67-county sale directory. Holder and lands-available tools return empty result sets — those datasets are not yet ingested. Auth via Bearer. Standard MCP-1.0 JSON-RPC. $5/mo for 1K calls, perfect for prototyping and it scales when you go to market.

Built like an API you'd actually wire up

Boring on purpose

tools/list

Standard MCP-1.0 JSON-RPC. Lists all 8 Florida tax-certificate tools, their schemas, and arg shapes — drop-in introspection for any client.

Ask: “Call POST /mcp with method 'tools/list' to discover available Florida tax-certificate tools at runtime.”

Bearer auth

One header. No OAuth dance, no signed requests. Issue per-agent keys; rotate or revoke from the dashboard.

Ask: “Authorization: Bearer fltc_live_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx”

JSON-RPC over HTTP

Same envelope shape as the REST API. JSON in, JSON out. Streamable responses where it matters (large certificate searches).

Ask: “{ "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "search_certificates", "arguments": { "holder": "acme" } } }”

Three configs, same endpoint

Pick the client. Paste the snippet.

Edit your Claude Desktop config (Mac: ~/Library/Application Support/Claude/claude_desktop_config.json — Windows: %APPDATA%\Claude\claude_desktop_config.json), then restart Claude.

json

{
  "mcpServers": {
    "florida-tax-cert-api": {
      "url": "https://fltaxcerts.com/api/mcp",
      "headers": {
        "Authorization": "Bearer fltc_live_REPLACE_WITH_YOUR_KEY"
      }
    }
  }
}

Restart Claude Desktop. The 8 Florida property tools appear in your tool list.

Or skip the client entirely

It's just HTTP + JSON-RPC

Discover the tools

A single tools/list call returns every tool, its schema, and arg types.

GET/mcp

curl -H "Authorization: Bearer fltc_test_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" \
     "https://fltaxcerts.com/mcp"

Sample response shape

Tool-call results return the same envelope shape as the REST API: data, meta, pagination cursors.

JSONcertificates-search.json

Synthetic rows — the live response from /api/v1/sample/certificates/search. Not real records.

Standards, not lock-in

Open MCP spec. Works with any MCP-1.0 client today; modelcontextprotocol.io.
Bearer auth. Per-agent keys, scoped, rotatable. No OAuth choreography.
8 tools, extension PRs welcome. The tool surface is versioned; open a PR if you need a new endpoint and we'll add it on the same MCP server.

$5/mo for prototyping. Tiered when you ship.

1,000 calls a month included. Higher tiers when your agent goes to production. No retainer, no minimum, cancel anytime.
