Circle Agent Stack MCP
MCP wrapper around Circle's Agent Stack — create USDC wallets, set spend policies, send stablecoin, and pay x402-gated endpoints.
Last release Jun 4, 2026 · Last commit Jun 4, 2026 · ★ 1
Overview
This MCP server wraps Circle's official Agent Stack CLI as tool calls: creating dev/hosted/smart wallets, setting daily spend caps, sending USDC, and paying x402-priced API endpoints from a coding assistant. It has 2 releases (latest v0.1.3, June 2026), tests, and a Dockerfile — a thin, documented layer over Circle's own infrastructure rather than a standalone custody system.

This is the share of our daily checks that succeeded — not an availability guarantee. A check can fail because the host was down, because our runner timed out, or because the network in between dropped it, and only the first of those is a fact about this project. Failures are split by what we can attribute; anything we cannot attribute is counted, not hidden. 44 of these checks predate 2026-09-01, when the probe counted a bot-block (HTTP 403) as a failure and recorded no reason for any failure. Rates spanning that date mix two definitions. Since then: 100%.
