Claude Code

Add the server

claude mcp add --transport http seesaw https://api.seesaw.fun/mcp \
  --header "Authorization: Bearer sspat_YOUR_KEY"

Add --scope user to make it available in every project (default is the current project only).

Inside a Claude Code session:

/mcp

You should see seesaw listed as connected with 14 tools. Then try a natural-language query:

What’s trending on SeeSaw right now?

Claude should call list_topics and summarize live markets.

Symptom	Likely cause
`401` / auth error	Key typo, missing `Bearer` prefix, or the key was revoked
`404` on connect	URL typo — the endpoint is exactly `https://api.seesaw.fun/mcp`
Tool errors mentioning retry	Rate limited — see Rate limits
Server not listed	Re-run `claude mcp add`, then restart the session

To remove or re-add:
