{"entry":{"slug":"agentguard-mcp","name":"agentguard","category":"mcp","summary":"Hosted MCP policy proxy for agent fleets: per-run spend caps, kill switch, loop breaker, dry-run of destructive writes with a diff, and a hash-chained audit log.","description":"agentguard hosted is a hard stop between an agent fleet and the bill: spend caps and a kill switch per run, loops broken before they bill, destructive writes faked in dry-run with the diff, and a hash-chained audit log with published daily Merkle roots. agentguard_get_pricing and agentguard_spend_report need no key; agentguard_spend_report reads an agent log (Claude Code .jsonl, CSV or an agentguard audit export) and reports spend, loops and the band whose cap would have stopped each overspend, storing nothing. An agent can start the free trial with no human and no card: POST https://agentwares-agentguard.vercel.app/api/v1/signup {\"accept_terms\": true} returns an account key; then agentguard_create_proxy puts a per-customer proxy in front of an MCP server. Every refusal is an isError result whose text is JSON {code, cause, fix, retryable}: LOOP_DETECTED, CAP_EXCEEDED, BAND_EXCEEDED, APPROVAL_REQUIRED, KILL_SWITCH, TOOL_DENIED. Monthly bands are bought at a Stripe Checkout page by a person; an unattended agent can instead buy calls outright at $0.00029/call with a prepaid credit key funded in USDC over x402.
