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 | $0.00968 | $0.00968 |
| Opus 5.5 | $0.00387 | $0.00387 |
| Sonnet 5.5 | $0.00194 | $0.00194 |
| Haiku 4.5 | $0.00097 | $0.00097 |
Grade A, and why
agentdocs-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 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 — 67 lines — stays where its author put it; the contents beside it link to each section on GitHub.

What this is
agentdocs-mcp — the stdio MCP server for AgentDocs, published to npm
and listed in the official MCP registry as io.github.hoornet/agentdocs-mcp. It gives MCP clients
read/search/write access to AgentDocs Markdown docs.
ESM ("type": "module"), TypeScript, Node >=20, no runtime framework. Dependencies are just
@modelcontextprotocol/sdk and zod.

official MCP registry manifest — version must match the published npm version |
Build with npm run build (tsc → dist/). npm run watch for incremental.
Two invariants that have each caused a shipped bug
1. The version lives in package.json and nowhere else.
src/index.ts derives it at runtime via createRequire(import.meta.url)("../package.json").version.
Do not "simplify" this into a hardcoded VERSION string. A hand-maintained literal is precisely
what silently drifted two releases behind and made 0.6.0/0.6.1 report 0.5.2 to every client in the
MCP initialize handshake. Fixed in 0.6.2 — keep it derived.
2. Never trust a lifecycle hook to produce the build.
Publish with npm run release (= npm run build && npm publish), not bare npm publish.
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.
