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 | $0.00942 | $0.00942 |
| Opus 5.5 | $0.00377 | $0.00377 |
| Sonnet 5.5 | $0.00188 | $0.00188 |
| Haiku 4.5 | $0.00094 | $0.00094 |
Grade A, and why
historia-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 13d 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.
This is a copy
98% identical to afya-ya-akili-mcp AGENTS.md — 7 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts

What this is
Kenya and Africa historical archives via MCP. 6 tools.
Read first
- README.md
- agent-context.json
- Portfolio reasoning standard: https://github.com/gabrielmahia/nairobi-stack/blob/main/docs/COVERAGE_ADAPTIVE_REASONING.md
Critical rules
- Truth labels: never present synthetic, simulated, demo or hand-compiled data as real or verified. Mark it in the data itself (
synthetic: true, asourcethat says so) and in the README. If a real source cannot be cited with an as-of date, the output must say so. - Any number a user might act on (tax rates and limits, phone numbers, emergency lines) needs a primary source or two independent listings, with the date checked in the
sourcefield. Unverifiable entries are removed, never labelled 'DEMO - verified'. - The README tool table must list exactly the tools the server exposes; do not hard-code server counts. Keep
<!-- mcp-name: io.github.gabrielmahia/historia-mcp -->in the README: the MCP registry refuses a release without it. - Every tool declares MCP annotations (
readOnlyHint,idempotentHint,openWorldHint;destructiveHintfor anything that sends money or messages, or writes). Read-only means no side effects. - CI installs this repository's code (never the published package) on Python 3.10-3.14; lint failures are real (no
|| true). Python 3.10 reaches end of life on 2026-10-31: drop it then. - Releases are tag-driven and tokenless: bump
versionin pyproject.toml and server.json together, merge to main, push tagvX.Y.Z; the Publish workflow (test, PyPI Trusted Publisher, MCP registry) does the rest. PyPI releases are immutable. After a release runscripts/glama_sync.py --applyfrom nature-ai-evolution-lab to regenerate glama.json from the running server (a weekly audit flags drift). - The pyproject
descriptionmust be a complete sentence naming what the tools do: it is what PyPI, the MCP registry and Glama show (six were once cut off mid-word at 80 characters). Do not hard-code tool counts in it. - Prefer a bundled, dated, sourced snapshot (offline-first) over live calls that can hang; never call an endpoint that has not been verified to exist.
- At the tool boundary return errors to the model as data instead of crashing the server; a broad
exceptneeds# noqa: BLE001and a reason.
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.
