Use okdata in Claude: a custom connector on the web and desktop

Connect it

1. Open the place MCP servers are added. Customize → Connectors → Add → Add custom connector. On Team and Enterprise an Owner adds it first under Organization settings → Connectors → Add → Custom → Web; members then choose Connect.
2. Fill in the fields. The key is typed into the client and stays there.

   Field	Value
   Name	okdata
   Remote MCP server URL	https://api.okdata.online/mcp
   Authentication	No sign-in
   Request headers	authorization, value Bearer okd_…. Claude adds no prefix, so type “Bearer ” yourself.

3. Choose Add, then Connect if Claude shows it. In a chat, open + → Connectors and switch okdata on.
4. Ask it to list the tools. The reply should match the one below.

Check it works

“List the okdata tools.”

okdata is connected with 5 tools: find describe the data you need in words; get up to five capabilities with what they need, the price and a ready call. It never offers another platform in place of the one asked for; describe read the full contract of one to five capabilities: parameters, links taken, price and the most a call can cost, paging, fields and an example item; call fetch one page of data as text: the first lines say what it cost, the balance left and how to get the next page. Failed calls are free; max_price caps a call; read_more read the rest of an answer that was cut at about 20 KB, or the same result in another view, for 24 hours; account balance and the key’s spending limits, a receipt for one call, usage by day or capability; which capabilities are up, even without a key. Only call costs money. The catalog has 214 endpoints on 17 platforms.

None of this costs anything.

A first conversation

“What is on Weibo hot search right now?”

2 tool calls · 1 charged · $0.002

Then try: “Use okdata to show me what is on Weibo's hot search right now.”

Tips for Claude (web and desktop connector)

• Let the free tools run without asking. Allow find, describe and account; keep call on “ask” if you want to approve every charge.
• Ask for the cost first. “Tell me what this will cost before you call anything” works in every client.
• Give each client its own key. Create one per app in the console; revoking it then touches nothing else.
• Retries are safe. A resent call with the same idempotency_key is never charged twice, and failed calls are free.

What to know about Claude (web and desktop connector)

• Request headers are a beta that Claude offers to a limited set of organisations. Without it, Claude can only connect by signing in (OAuth), and okdata sign-in for connectors is still being built. Until then, use Claude Code, or Claude Desktop through the bridge on the Claude Desktop page.
• Custom connectors work on every plan; the Free plan allows one.
• A connector's authentication cannot be changed after it is added: remove it and add it again.
• Claude connects from Anthropic's cloud, not from your computer, so the server address must be public. Ours is.
