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 | $0.00306 | $0.00306 |
| Opus 5.5 | $0.00122 | $0.00122 |
| Sonnet 5.5 | $0.00061 | $0.00061 |
| Haiku 4.5 | $0.00031 | $0.00031 |
Grade A, and why
uk-business-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.
What it actually says
uk-business-mcp (Ledgerhall proxy)
FastMCP proxy that bundles govuk-mcp, uk-legal-mcp, uk-due-diligence-mcp,
and property-shared behind a single URL. Marketed as the Ledgerhall
product on bouch.dev.

This repo has no domain tools of its own — it only proxies upstreams via
create_proxy(). All tool logic lives in the upstream servers.
Not to be confused with
uk-due-diligence-mcp is a DIFFERENT repo at /home/bch/dev/uk-due-diligence-mcp,
deployed at https://uk-due-diligence-mcp.fly.dev/mcp. That repo is the
standalone Companies House / Charity / HMLR / Gazette / sanctions server with 18 tools.
It is one of the upstreams this proxy mounts, not the same thing as this proxy.
The due-diligence folder was previously misleadingly named
/home/bch/dev/uk-business-mcp until 2026-04-14, which was the source of
repeated cross-repo confusion.
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.
