Connect TAM Tool to Claude
TAM Tool ships a remote MCP (Model Context Protocol) server. Connect it once and Claude can pull establishment counts, wages, GDP, supply-chain flows, and public comps into any conversation — every number cited to its federal source.
The server endpoint is:
https://mcp.tamtool.com/mcpIt uses streamable HTTP transport with OAuth sign-in — when you connect, your browser opens the TAM Tool login page and the connector authenticates as your account. You'll need a TAM Tool account first. No API keys or client credentials to copy — the OAuth flow is discovered automatically.
Claude (claude.ai and Claude Desktop)
Web and desktop share the same connector settings:
- Open Settings → Connectors and click Add custom connector.
- Name it TAM Tool and paste the server endpoint above into the URL field.
- Click Add, then Connect — your browser opens the TAM Tool sign-in page. Sign in with your TAM Tool email and password.
- In a chat, open the search-and-tools menu and make sure the TAM Tool connector is enabled.
Claude Code
Add the server from your terminal:
claude mcp add --transport http tam https://mcp.tamtool.com/mcp
Then run /mcp inside a Claude Code session and pick tam to
complete the browser sign-in.
Verify it works
Ask Claude something only the data can answer:
How many landscaping businesses are there in the US,
and what does their typical worker earn?
You should see Claude call get_segment_summary and
top_occupations_for_industry and come back with sourced figures
(Census CBP 2022, BLS OEWS May 2024). You can also check the server itself at
/health on the endpoint host.

Example prompts
- "Size the TAM for software sold to independent veterinary clinics. Show your work."
- "Which industries have the most establishments in the 20–99 employee band, and what would a $200/mo tool's TAM be in each?"

- "Find public SaaS comps for vertical software in construction and pull their revenue growth."
Troubleshooting
401 or "authentication required" mid-conversation — access tokens last one hour
and refresh automatically for 30 days; past that, reconnect the connector (claude.ai) or re-run
/mcp (Claude Code).
Connector won't add — confirm the URL ends in /mcp and the client ID
and secret are set under Advanced settings.
