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 | $0.02332 | $0.02332 |
| Opus 5.5 | $0.00933 | $0.00933 |
| Sonnet 5.5 | $0.00466 | $0.00466 |
| Haiku 4.5 | $0.00233 | $0.00233 |
Grade A, and why
faxdrop-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 2d 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 — 215 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
This repository is faxdrop-mcp — a Model Context Protocol server that
wraps the FaxDrop HTTP API so AI assistants can
send real faxes (single tool: fax_send; one prompt template).
This file is the canonical source of truth for any AI agent that edits the code in this repository. Read it before making changes. It encodes the conventions the maintainers actually enforce — not aspirations.
If you are an installation agent (i.e. helping a user install the MCP server in their client config rather than edit the server code), stop reading this file and read
llms-install.mdinstead. That file is for the install audience; this one is for code-editing agents.
Audience boundary
| Audience | Source of truth |
|---|---|
| Edits this repo's code | AGENTS.md (you are here) |
| Installs this MCP into a client config | llms-install.md |
| Threat model / security argument | docs/ASSURANCE_CASE.md |
| Disaster recovery / continuity | docs/CONTINUITY.md |
| Forward-looking work | docs/ROADMAP.md |
| End-user features and install commands | README.md |
| Vulnerability reporting | .github/SECURITY.md |
Do not duplicate what those documents say. Reference them.
Setup
Node >=24.18.1 is enforced via engines + engine-strict=true in
.npmrc. CI runs the matrix on Node 24 and 26. npm install on Node
22 fails immediately — that is intentional.
npm install
This repo uses npm, not pnpm. Lockfile is package-lock.json.
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.

faxdrop-mcp AGENTS.md is an instructions file published in the GitHub repository klodr/faxdrop-mcp (5 stars, last pushed yesterday), licensed MIT. It adds 2,332 tokens to every session, about $0.0093 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.
