I built budget controls for AI agents, does this solve a problem you actually have?", "summary": "A developer built gvnr, an open-source MCP server that provides per-agent spend caps and a human approval gate for AI agents. The tool hard-stops agent calls when budgets are exhausted and sends mobile approval links for irreversible actions, operating as REST calls or MCP tools without requiring a platform or SDK.", "body_md": "been building AI agent infrastructure for the past few months. The two things that kept biting me —\n\nand kept coming up when I talked to other devs building agents — were runaway costs and agents doing\n\nirreversible things without asking first.\n\nSo I built gvnr: an open-source MCP server that gives agents per-agent spend caps (hard-stop before a\n\ncall if the budget's gone) and a human approval gate (agent asks, you get a mobile link, you approve or\n\ndeny, agent waits). Both work as plain REST calls or MCP tools — no platform to adopt, no SDK.\n\nIt's live. You can get an API key in one curl command and try the approval gate for free (it doesn't burn\n\nthe trial ops).
