What is bsv-mcp CLAUDE.md?

Repository instructions for bsv-mcp, a server that lets AI assistants work with Bitcoin SV blockchain features. They cover setup, local development, testing, linting, and three deployment modes.

Use them when developing wallet, token, ordinal, identity, or social features, or when running the server locally, over HTTP, or as a Cloudflare Worker.

They give an agent the project-specific commands and constraints needed to build, run, check, and deploy the server correctly.

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.

Model	Per session	Once invoked
Fable 5.1	$0.01693	$0.01693
Opus 5.5	$0.00677	$0.00677
Sonnet 5.5	$0.00339	$0.00339

Security

Grade A, and why

bsv-mcp CLAUDE.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 1mo 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.

Project overview

BSV MCP is an open-source Model Context Protocol server for Bitcoin SV. It contains the published MCP package and the Next.js site that documents and hosts the remote MCP endpoint.

Current product decisions — September 8, 2026

These decisions supersede older OAuth and architecture proposals.

Local stdio MCP is the active product. It requires no Sigma sign-in.
Hosted MCP, its authorization server, and HTTP spending approval are deferred. Existing HTTP code is legacy implementation, not an instruction to finish it.
Sigma Connect is optional and requires explicit user consent. It is separate from MCP authentication and from the wallet. Do not change Sigma Auth or its database to make BSV MCP work.
A future hosted authorization server would belong to bsvmcp.com itself. This is a deferred direction, not an active implementation task.
Local browser setup, an external wallet's signing API, and 1Sat service calls may use HTTP. They do not make BSV MCP a remotely hosted MCP product.
The latest user decisions govern. Internal WORKLIST and the recent Sigma handoff are supporting references; old checkboxes are not authorization.

The website and legacy HTTP routes still contain contradictions with these choices. Correct them through the current reconciliation plan; do not treat passing tests or deployed behavior as proof of the intended product scope.

The retired Cloudflare worker and OpenNext configuration were removed. Do not reintroduce a Cloudflare deployment path unless the product owner explicitly requests one.

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.
