@modelcontextprotocol/server-budget-allocator

Implements the Model Context Protocol (MCP) server specification, enabling Claude and other LLM clients to invoke budget allocation functions through a standardized message-based interface. Uses MCP's tool definition schema to expose budget operations as callable resources with strict input validation and response formatting, enforcing budget constraints at the protocol level rather than application level.

Provides a web-based visualization dashboard that renders budget allocation state and updates in real-time as allocations change. Uses a client-server architecture where the MCP server broadcasts allocation events to connected visualization clients, likely via WebSocket or Server-Sent Events, enabling stakeholders to monitor budget distribution without polling or manual refresh.

Validates all budget allocation requests against defined constraints (total budget limits, per-category limits, minimum/maximum allocation thresholds) before execution. Implements constraint checking as a middleware layer in the MCP request pipeline, rejecting invalid allocations with detailed error messages that explain which constraint was violated and by how much.

Maintains a transactional ledger of all budget allocations, tracking allocation history, current balances, and state transitions. Implements ACID-like semantics for allocation operations, ensuring that partial failures don't leave the budget state inconsistent. Uses an in-memory or persistent store to track allocations and provides query interfaces for retrieving allocation history, current balances, and audit trails.

Supports multiple concurrent users or agents making budget allocation decisions with role-based access control (RBAC) to restrict who can allocate what amounts or categories. Implements authorization checks in the MCP request handler, verifying that the requesting user/agent has permission to perform the requested allocation before execution. Tracks allocation requests by user/agent identity for accountability.

Provides detailed explanations of budget allocation decisions made by Claude or other LLM agents, including the reasoning, constraints considered, and alternative allocations that were rejected. Captures the LLM's chain-of-thought or decision rationale and surfaces it through the MCP interface, enabling stakeholders to understand why specific allocations were chosen and audit the decision-making process.
