Access, auth, and limits
Authentication accepts either an x-api-key header or OAuth. The API key path works immediately: the key is provisioned on signup and needs no separate MCP setup.
An unauthenticated request returns a correct 401 carrying a WWW-Authenticate challenge, the mcp:tools scope and a resource_metadata pointer to the OAuth discovery document. That is the specified behaviour and it is rarer than it should be, so a 401 here is proof the endpoint exists rather than a sign it is missing.
Error handling at the MCP layer is better than at the REST layer. A call with a missing required argument came back as a readable 422 naming the failing field, where the REST API returns a bare 400 with no message.
Where it works and what to build
HasData links integration guides for CLI, MCP Server, OpenClaw, Agent Skill and n8n directly from the API Keys page in the dashboard, which is a clear signal about the workflows it expects to serve.
Because the server is remote streamable HTTP with standard auth, it fits the usual remote-MCP setup rather than needing a local bridge process.
How to connect HasData MCP to Claude Desktop
Add this block to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows), then restart Claude Desktop. Cursor and Codex use a similar schema.
{
"mcpServers": {
"hasdata": {
"command": "npx",
"args": ["mcp-remote", "<YOUR_MCP_URL>"]
}
}
}
// HTTP-transport MCP. Get your <YOUR_MCP_URL> from the vendor dashboard.
// Server source: https://mcp.hasdata.com/mcp
// Claude Code (one-liner): claude mcp add hasdata <YOUR_MCP_URL> --transport httpSome MCP servers require an API key. Check the source page for setup: mcp.hasdata.com/mcp.
Does HasData MCP cost extra?
HasData ships an official MCP server that uses your existing subscription credentials.
- No separate MCP licence to buy. You pay for your HasData plan, the MCP server queries that account.
- Whether it's gated to a specific tier wasn't extracted automatically — verify the access requirements on the MCP page or pricing docs.
HasData also publishes a REST API
HasData publishes an API, but per-tier gating wasn't extracted automatically.
See HasData API pageWhat you can do with HasData from an AI agent
Three shapes of agent workflow. Pick the row that matches how you actually use Claude / Cursor / Codex day to day.
Skip the dashboard, ask Claude
- "What keywords moved this week?" answered in seconds
- Quick one-off questions without leaving the editor
- Pipe HasData data into your personal notes / docs without writing a script
Run client analysis at agent speed
- Hand the MCP server to your team — every consultant can ask Claude about any client's HasData account
- Multi-account workflows without context-switching the HasData UI
- Reports you'd normally spend hours on, done before standup
Production agent workflows
- Embed in your internal Codex / Cursor agents that triage HasData data daily
- Combine with other MCP servers in a multi-step agent chain
- Constrain agents to read-only roles to keep production HasData safe
Limits and gotchas
- Official MCP server — published by HasData themselves, so it should track product changes.
- Fallback: the REST API works for any flow the MCP server doesn't cover.
- Rate limits: MCP calls count against your underlying HasData API quota. Burst usage from a curious agent can drain a daily allowance fast.
