What your agent can do

Belvo gives your agent 24 tools it calls directly β€” pick the ones it needs, in Claude, Cursor, or any MCP client.

  • list_institutions β€” List available financial institutions
  • create_link β€” Create a link to a financial institution
  • list_links β€” List existing links
Example call
// Your agent calls a tool directly β€” no glue code.
// CodeSpar's managed tier handles OAuth2, token rotation and rate limits.
const result = await session.call("list_institutions", { /* ... */ });

Install

terminal
$ npm install @codespar/mcp-belvo

Quickstart

Add this entry to your claude_desktop_config.json (or any MCP-compatible client config).

{
  "mcpServers": {
    "belvo": {
      "command": "npx",
      "args": [
        "-y",
        "@codespar/mcp-belvo"
      ],
      "env": {
        "BELVO_SECRET_ID": "<your_belvo_secret_id>",
