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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00000 | $0.00331 |
| Opus 5 | $0.00000 | $0.00166 |
| Sonnet 5 | $0.00000 | $0.00066 |
| Haiku 4.5 | $0.00000 | $0.00033 |
Grade A, and why
new-tool 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 10d 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
Adding a New MCP Tool
Follow this exact pattern when adding a new tool. Do not invent new registration patterns or file structures.
Steps
-
Implement in
src/tools/<category>.ts- Define a Zod schema for the tool's parameters using validators from
src/utils/validators.ts - Add the handler inside the existing
register*Tools(server, exchangeManager)function - Return
{ content: [{ type: 'text', text: JSON.stringify(...) }] }
- Define a Zod schema for the tool's parameters using validators from
-
Register in
src/tools/index.ts- If you created a new category file, import and call its
register*Tools()function here - Existing categories (market-data, account, trading, cardano, strategy) are already wired up
- If you created a new category file, import and call its
-
Update README.md
- Add the tool to the tools table with name, description, and parameters
- Assign a pricing tier: free (
list_exchangesonly), read ($0.001), or write ($0.01)
-
Add pricing in
src/payment/index.ts- Add the tool name to the appropriate tier in
TOOL_PRICING
- Add the tool name to the appropriate tier in
-
Add unit test in
src/tests/- Mock the exchange connector via
getConnectorSafe() - Test parameter validation and expected output shape
- Mock the exchange connector via
Do NOT
- Create new files under
src/for a single tool — add to the matching category file - Use
require()— this project is ESM (NodeNext) - Skip
npm run typecheckafter 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.

new-tool is a skill published in the GitHub repository QBT-Labs/openmm-mcp (3 stars, last pushed yesterday), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 331 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
