Delegare provides an official MCP Server that enables LLMs (like Claude or GPT-4) to perform economic actions autonomously using Intent Mandates. The server is available in the packages/mcp-server directory of the Vault repository.

​
Available Tools

The MCP server exposes the following tools to the agent:

​
1. setup_spending_mandate

Generates a setup URL for the human user.
  • Input: maxAmountPerTxCents, maxMonthlySpendCents, railPreference
  • Output: A markdown link for the user to authorize.

​
2. check_mandate_balance

Allows the agent to see how much it can spend.
  • Input: mandateId
  • Output: Remaining monthly balance.

​
3. authorize_agent_payment

The core tool for making purchases.
  • Input: amountCents, currency, description, recipient
  • Output: A cryptographic Intent Mandate (SD-JWT-VC) or a success receipt if the server handles the execution.

​
MCP Authentication Guard

To prevent unauthorized tool calls, the MCP server implements an mcpAuthGuard.
  • Every tool call must be authorized by an OAuth session.
  • Credentials (merchantId, apiKey) are never exposed to the LLM prompt.
  • The guard injects the required metadata into the tool context based on the bearer token in the request header.
