mcp-connector

Read-only TallyPrime MCP. Cursor asks accounting questions; this server fetches live company data over Tally XML Export. Nothing is created, altered, or deleted in Tally.

Flow:

Cursor → Streamable HTTP MCP → Node → TallyPrime

Setup

Copy .env.example to .env next to tally.js and server.js:

TALLY_URL=http://192.168.29.149:9000
HOST=0.0.0.0
PORT=3000

TALLY_URL is the TallyPrime HTTP port on the Tally PC (9000). Do not expose that port to the internet.

npm install
node server.js

Health: GET http://127.0.0.1:3000/health
MCP: POST http://127.0.0.1:3000/mcp

STDIO (optional): node server.js --stdio

Tally connectivity check: node test-tally.js

Related MCP server: Tally Prime MCP Server

Remote Cursor

On another PC on the LAN, add this MCP server (this machine’s LAN IP is 192.168.29.47):

{
  "mcpServers": {
    "tally": {
      "url": "http://192.168.29.47:3000/mcp"
    }
  }
}

Allow inbound TCP 3000 on this PC. Keep Tally port 9000 local.

Tools

Four tools, not one per report:

Dates should match the loaded Tally financial year. Pass financialYear such as 26-27, or explicit fromDate / toDate as YYYY-MM-DD.
