-## Available Tools
+## What's Available
+
+Connecting to the MCP server gives your AI assistant two things: **tools** that call the Whitepages Pro API, and the **full corpus of documentation**.
+
+### Data tools
+
+These tools make live, metered calls to the Whitepages Pro API:
+
+- **Person search** — look up people by name, phone, or address
+- **Person by ID** — retrieve full detail for a specific person
+- **Property search** — look up properties by address
+- **Property by ID** — retrieve full detail for a specific property
+- **Account usage** — report your API usage over a date range
+
+Each tool bills identically to the equivalent REST endpoint — see [Billing](/references/billing).
+
+### Documentation
+
+The complete Whitepages Pro API documentation is available directly through the MCP server, in two forms that expose the same content:
+
+- **MCP resources** — for assistants that support resources, every document is addressable as a resource that can be browsed and attached directly.
+- **Documentation tools** — for assistants that don't support resources, the same corpus is reachable through the `list_documentation`, `search_documentation`, and `get_documentation` tools.
+
+Because both forms serve the identical corpus, no assistant is left without the documentation.
+
+<Callout type="info">
+  Some MCP clients don't currently support MCP resources — including the
+  Anthropic products **Claude Code**, **Claude Desktop**, and **Co-Work**. This
+  is a limitation of those harnesses' MCP support, not of the Whitepages MCP
+  server or its resources. On these clients, the documentation tools
+  (`list_documentation`, `search_documentation`, `get_documentation`) provide
+  the same complete corpus.
