A read-only, stateless MCP server providing on-chain monitoring tools for AI agents.

The service accesses public RPCs and DefiLlama data, charging per call via USDC on Base or prepaid credits, with no data storage or financial advice provided.

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 fabtally-chain-mcp https://chain.fabtally.com/mcp

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 fabtally-chain-mcp --url https://chain.fabtally.com/mcp

Cursor

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

Cursor configuration

{
  "mcpServers": {
    "fabtally-chain-mcp": {
      "url": "https://chain.fabtally.com/mcp"
    }
  }
}

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": {
    "fabtally-chain-mcp": {
      "type": "streamableHttp",
      "url": "https://chain.fabtally.com/mcp",
      "disabled": false
    }
  }
}

VS Code

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

  "servers": {
    "fabtally-chain-mcp": {
      "type": "http",
      "url": "https://chain.fabtally.com/mcp"

Gemini CLI configuration

gemini mcp add --transport http fabtally-chain-mcp https://chain.fabtally.com/mcp

Claude Desktop

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