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 | $0.00647 | $0.00647 |
| Opus 5.5 | $0.00259 | $0.00259 |
| Sonnet 5.5 | $0.00129 | $0.00129 |
| Haiku 4.5 | $0.00065 | $0.00065 |
Grade A, and why
bitcoin-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 2mo 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.
How it starts
The opening of the file, as written. The whole thing — 37 lines — stays where its author put it; the contents beside it link to each section on GitHub.
bitcoin-mcp — MCP Server for Bitcoin
What this is
MCP server wrapping Bitcoin Core/Knots RPC. It auto-detects a local node and can use a compatible remote API when SATOSHI_API_URL is configured. The former public service at bitcoinsapi.com is paused and is not a working default. Published to PyPI and Smithery.
Key files
src/bitcoin_mcp/server.py— 50 standard tools plus one conditional remote-API tool, defined as@mcp.tool()decoratorssrc/bitcoin_mcp/l402_client.py— L402 payment channel clienttests/— test suite, must pass before any release.github/copilot-instructions.md— GitHub Copilot/Coding Agent guidance

Development rules
- Bump version in
pyproject.tomlfor any release (semver) - Run
pytest tests/before any commit - Tools must work against both local Bitcoin Core/Knots and explicitly configured Satoshi API-compatible backends
- No breaking changes to tool signatures without a major version bump
- Tool docstrings appear in MCP client UIs — keep them accurate and useful
- Discoverability matters: Glama/Smithery rank by stars + docs. Keep README and per-tool examples current.
- Keep optional Satoshi API integration docs aligned with https://github.com/Bortlesboat/bitcoin-api/blob/master/docs/AGENT_INTEGRATION.md
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.
