stackapps-suite-mcp
mcp-name: io.github.Explorer-64/stackapps-suite-mcp
One MCP server for the whole StackApps tool suite. Pay per call in USDC on Base mainnet via x402 — no account, no API key, no signup. Member apps (Imagcon, StackBill, Dicta-Notes) contribute tools; one install covers the suite.
Install
The package is self-hosted (not on PyPI). Install directly from the release wheel documented in the live blueprint:
claude mcp add stackapps-suite -- uvx --from https://github.com/Explorer-64/StackApps/releases/download/stackapps-suite-mcp-v0.1.9/stackapps_suite_mcp-0.1.9-py3-none-any.whl stackapps-suite-mcp --wallet-key 0x...Or in any MCP client config (Claude Desktop, Cursor, Windsurf, Cline):
{"mcpServers": { "stackapps-suite": { "command": "uvx", "args": [ "--from", "https://github.com/Explorer-64/StackApps/releases/download/stackapps-suite-mcp-v0.1.9/stackapps_suite_mcp-0.1.9-py3-none-any.whl", "stackapps-suite-mcp" ], "env": { "WALLET_PRIVATE_KEY": "0x..." } } } }
Requirements: uv, Python 3.11+, an EVM wallet holding USDC on Base mainnet (eip155:8453). Prefer the WALLET_PRIVATE_KEY env var over the --wallet-key argument.
Always verify the current install URL and version at mcp.stackapps.app/blueprint.txt.

Payment safety
The server refuses to sign any payment challenge that does not pay the StackApps suite wallet, or that exceeds the per-call cap ($0.59 USDC by default; override with STACKAPPS_MAX_USD_PER_CALL). A compromised or spoofed endpoint cannot redirect or inflate payments. Payments settle on-chain via EIP-3009 — the gas is sponsored; your wallet needs only USDC.
Never commit your wallet key, and never run this server on a public host with WALLET_PRIVATE_KEY set. The hosted endpoint at mcp.stackapps.app serves discovery metadata only.
