Firecent MCP Server

MCP (Model Context Protocol) server for Firecent — a personal finance app (Next.js 16 + Prisma 7 + PostgreSQL).

This server lets AI agents (like Hermes) read and manage financial data through Firecent's REST API:

• Accounts — list, get, create

• Records — list, get, create transactions (income, expense, transfer)

• Categories — list, get, create

• Query — flexible query endpoint

• Info — API key + permissions validation

Architecture

Same pattern as iris-mcp:

firecent-mcp/
