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 | $0.00298 | $0.00298 |
| Opus 5.5 | $0.00119 | $0.00119 |
| Sonnet 5.5 | $0.00060 | $0.00060 |
| Haiku 4.5 | $0.00030 | $0.00030 |
Grade A, and why
units-static 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 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.
What it actually says
units-static — Agent Guide
Purpose
High-quality static unit conversion MCP server used as the “good MCP” dogfood for Plugin Federation (judges should score high; CI fails on judge fail and eval misses).
Tools
| Tool | Description |
|---|---|
list_units |
Catalog of unit ids by dimension |
convert_length |
Length conversion |
convert_mass |
Mass conversion |
convert_temperature |
Temperature conversion |
convert_volume |
Volume conversion |
compare_quantities |
Same-dimension comparison |
Running
pip install -r requirements.txt
python src/server.py
Conventions
- Prefer deep tool/parameter descriptions over short stubs.
- Keep enums closed; never invent unit strings outside
list_units. - Keep output models object-shaped for MCP
outputSchema. - Do not add network-backed tools; this server is deterministic.

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.
