Attest MCP

The Attest connector allows AI assistants to interact with Attest records, including verifying agreements, checking statuses, reminding signers, preparing new agreements, recording receipts, and sharing proofs. It operates over the Model Context Protocol (MCP) and supports end-to-end encryption, ensuring documents remain private while the assistant handles metadata and workflow actions.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers a Streamable HTTP server. Use --scope project to write .mcp.json for the repo.

Claude Code configuration

claude mcp add --transport http attest-mcp-datahubz https://attest.datahubz.com/mcp/verify

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).

Codex configuration

codex mcp add attest-mcp-datahubz --url https://attest.datahubz.com/mcp/verify

Cursor

Merge this server into .cursor/mcp.json in your project, then enable attest-mcp-datahubz in your MCP settings.

Cursor configuration

{
  "mcpServers": {
    "attest-mcp-datahubz": {
      "url": "https://attest.datahubz.com/mcp/verify"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure). The type must be streamableHttp for a remote HTTP server.

Cline configuration

{
  "mcpServers": {
    "attest-mcp-datahubz": {
      "type": "streamableHttp",
      "url": "https://attest.datahubz.com/mcp/verify",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start attest-mcp-datahubz and inspect its tools.

VS Code configuration

{
  "servers": {
    "attest-mcp-datahubz": {
      "type": "http",
      "url": "https://attest.datahubz.com/mcp/verify"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.

Gemini CLI configuration

gemini mcp add --transport http attest-mcp-datahubz https://attest.datahubz.com/mcp/verify

Claude Desktop

Merge this into claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop.

Claude Desktop configuration

{
  "mcpServers": {
    "attest-mcp-datahubz": {
      "url": "https://attest.datahubz.com/mcp/verify"
    }
  }
}

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.

Windsurf configuration

{
  "mcpServers": {
    "attest-mcp-datahubz": {
      "serverUrl": "https://attest.datahubz.com/mcp/verify"
    }
  }
}

Ground your agent in cited data

Attest MCP gives your agent tools. Koskamo gives it reviewed, cited facts to check its answers against. Add it as a second MCP server; public reads need no API key.
