A Model Context Protocol server that exposes IBM Granite foundation models as pay-per-use tools via the x402 payment protocol. End users pay USDC on Solana per call — no IBM Cloud account of their own. The server operator supplies IBM credentials (WATSONX_*) and a receiving Solana wallet (MCP_SVM_PAYMENT_ADDRESS); callers supply only USDC. One free tool (ibm_granite_getting_started) explains prices and the flow before any p

Questions
What is the ibm-x402-mcp MCP server?
x402 pay-per-use MCP server for IBM Granite AI — chat, code, embeddings, analysis, and time-series forecasting. Pay USDC on Solana per call. No IBM Cloud account required.
Is ibm-x402-mcp safe to connect to an agent?
The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B.
What credentials does ibm-x402-mcp need?
It reads WATSONX_API_KEY from the environment. Give it a token scoped to the least it needs — an agent that can be talked into calling a tool can be talked into calling it with your credentials.
How does ibm-x402-mcp run?
It speaks stdio and streamable-http, so it runs as a local process your client starts. It is published on npm as @three-ws/ibm-x402-mcp at 1.1.4.
How current is this page?
The grade is for one exact copy of the source (2ab38e3695e0), read on 2026-10-10. The repository is watched and re-audited when it changes.
