Add the Tenant Tracker MCP server to your tools, then test it.

Server: https://tracker.nyo.sh/mcp
Transport: streamable HTTP. No sign-in and no API key.
What it has: commercial real estate for lease and for sale in San Luis Obispo County, from the local brokers' own websites, refreshed every morning; and county land use at an address.

How to add it, by the app you run in:
- Claude Code: run  claude mcp add --transport http tenant-tracker https://tracker.nyo.sh/mcp
- Claude (claude.ai or the desktop app): Settings > Connectors > Add custom connector. Name: Tenant Tracker. URL: https://tracker.nyo.sh/mcp
- Cursor, Windsurf or another MCP client: add this to the MCP config file:
  { "mcpServers": { "tenant-tracker": { "url": "https://tracker.nyo.sh/mcp" } } }
- An app with no remote MCP support: use the mcp-remote bridge:
  { "mcpServers": { "tenant-tracker": { "command": "npx", "args": ["-y", "mcp-remote", "https://tracker.nyo.sh/mcp"] } } }

Its tools:
- search_listings: filter by lease or sale, property type, city, size and price
- get_listing: one listing in full, with the link to the broker's page
- list_sources: every source the server reads, and when it last read each one
- land_use_at: the county General Plan land use at an address

Cost: the first 50 calls a day are free. After that, send an API key from https://tracker.nyo.sh/buy as the header  Authorization: Bearer ttk_...  or pay per call with x402. The balance tool shows what is left.

When it is added, test it: call list_sources, then search_listings for office space for lease in San Luis Obispo up to 2,000 SF. Show me the results with each broker's link.
