Build on TCS BaNCS

950 operations from the BaNCS Swagger, with tested guides, a Playground and an MCP server. Every call goes to a shared demo bank, so you can try them right away.

Guides

Multi-step flows on real operations, each tested against the demo bank.

Playground

Send one request with the headers filled in. The body editor checks your JSON against the endpoint's schema, and the answer opens in a viewer you can fold and search.

Open the Playground

Build & run

Describe a task. An agent writes the code, runs it in a sandbox against the demo bank and fixes it until it works. Every change to bank data waits for your approval.

Start a task

Connect an AI assistant

Claude Code, Claude Desktop, Cursor and other MCP clients reach every operation through four tools: list_apis, search_endpoints, get_api_schema and call_api.

How to connect

claude mcp add --transport http bancs https://apicookbook.vercel.app/api/mcp

MCP server

Connect an MCP client

Any MCP client (Claude Code, Claude Desktop, Cursor…) can use these tools over streamable HTTP. No key needed; requests are rate-limited per address. If your bank needs a BaNCS access token, send it in the Accesstoken header.

Endpoint: https://apicookbook.vercel.app/api/mcp

Claude Code:

claude mcp add --transport http bancs https://apicookbook.vercel.app/api/mcp

Other clients (JSON config):

{ "mcpServers": { "bancs": { "type": "http", "url": "https://apicookbook.vercel.app/api/mcp" } } }

Reads run at once. A write (POST, PUT, PATCH, DELETE) is not sent: call_api returns an approval link. Open it here, approve within 10 minutes, then the client calls call_api again with {"approval_id": …} for the result.
