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 | $0.00654 | $0.00654 |
| Opus 5.5 | $0.00262 | $0.00262 |
| Sonnet 5.5 | $0.00131 | $0.00131 |
| Haiku 4.5 | $0.00065 | $0.00065 |
Grade A, and why
mcp-servers 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 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 — 58 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md - mcp-servers (Go workspace)
Project Structure
This is a Go workspace containing multiple MCP (Model Context Protocol) servers. Each server lives in its own module subdirectory and is listed in go.work.
Validation
To validate changes in this repository, run the following automated checks:
- Linting:
make lint - Tests:
make test-short - Build all servers:
make build
All automated steps must pass before changes can be merged.
For changes to datasource scraping/parsing logic, also run live integration tests:
- Integration tests:
make test(omits-short— hits live supermarket sites, may be flaky)
Additionally, perform global manual quality checks, plus these project-specific checks:
- Environment variables: Check that env vars referenced in code are documented in the server's README.
- MCP tool definitions in sync: When changing tools, check all three locations are consistent:
internal/server/tools.go— authoritative tool registration (descriptions, parameters, options)manifest.json— tool list for MCPB distribution (every server must have one)README.md— user-facing tool documentation table
- server.json descriptions: Must be ≤100 characters (MCP registry rejects longer ones).
All steps must pass before changes can be merged.
Desloppify
Subjective LLM-based code review complementing golangci-lint. Local-only (not in CI).
make desloppify— scan for quality issuesdesloppify next— show priority fix queue.desloppify/is committed for state persistence across sessions- Exclude worktree directories when created:
desloppify exclude <worktree-dir>/
Coding Standards
Datasource Constructors
- Per-store wrappers (e.g.
NewHiyou) are thin: fill in the store-specificConfigand delegate to the generic constructor
Mocks (assets module)
assets/internal/assetcore/mocks/ contains generated mocks (via mockery) of the IconProvider, IllustrationProvider, and FontProvider interfaces from assets/internal/assetcore/provider.go. These files carry a // Code generated by mockery. DO NOT EDIT. header — never hand-edit them; change the source interface and regenerate instead.
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.

mcp-servers CLAUDE.md is an instructions file published in the GitHub repository jbeshir/mcp-servers (1 stars, last pushed 4d ago), licensed MIT. It adds 654 tokens to every session, about $0.0026 per session on Opus 5.5. 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.
