Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00411 | $0.00411 |
| Opus 5 | $0.00205 | $0.00205 |
| Sonnet 5 | $0.00082 | $0.00082 |
| Haiku 4.5 | $0.00041 | $0.00041 |
Grade A, and why
server 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.

Working Agreements
- All code changes require Code Reviewer review before merge
- Security Engineer signs off on auth, crypto, and external API changes
- Database Engineer signs off on schema changes
- Write outputs to
mcpambassador_docs/— not just chat - Update
mcpambassador_docs/status.mdafter completing any task - Append to
mcpambassador_docs/lessons-learned.md, never overwrite
Definition of Done — CI Gate (MANDATORY)
No code change is considered complete until ALL of the following pass locally:
pnpm -r build # All 8+ packages compile
pnpm -r lint # 0 errors (warnings OK)
pnpm format:check # All files match Prettier style
pnpm -r typecheck # tsc --noEmit passes in every package
pnpm -r test # All tests pass
If any step fails, the agent MUST fix the issue before calling the task complete.
These mirror the GitHub Actions CI workflow (.github/workflows/ci.yml).
Common gotchas
- Prettier: After editing ANY
.ts,.json, or.mdfile, runpnpm formatbefore committing - ESLint: The config is
eslint.config.js(ESLint 10 flat config). No.eslintrc.*files. - Typecheck: Each package has its own
tsconfig.jsonextendingtsconfig.base.json. Changes to shared types can break downstream packages. - Node version: CI runs on Node 20. Do not use APIs added after Node 20 (e.g.,
import.meta.dirnamerequires Node 21.2+).
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.

server AGENTS.md is an instructions file published in the GitHub repository mcpambassador/server (3 stars, last pushed 7d ago), licensed Apache-2.0. It adds 411 tokens to every session, about $0.0021 per session on Opus 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.
