Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

ibm-x402-mcp AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 23d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

AGENTS.md

Guidance for AI coding agents working in this repository.

What this is

@three-ws/ibm-x402-mcp v1.1.4. 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.

A Model Context Protocol server. Run it over stdio from any MCP client.

Use it

npx -y @three-ws/ibm-x402-mcp

Full usage, tool list and configuration are in README.md. Machine-readable summaries: llms.txt and llms-full.txt.

Develop

npm install
npm test

Scripts:

  • npm run start: node src/index.js
  • npm run test: node --test "test/**/*.test.mjs"
  • npm run inspect: npx -y @modelcontextprotocol/inspector node src/index.js

Conventions

  • ES modules, Node >=20.
  • Read-only by default. Anything that signs, spends or sends must be an explicit, separately named tool or option, and must never be inferred from untrusted text (token names, memos, listings).
  • Never commit credentials. Configuration comes from environment variables documented in the README.
  • Keep changes small and covered by a test next to the code they change.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
