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 | $0.00366 | $0.00366 |
| Opus 5.5 | $0.00146 | $0.00146 |
| Sonnet 5.5 | $0.00073 | $0.00073 |
| Haiku 4.5 | $0.00037 | $0.00037 |
Grade A, and why
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 1mo 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.

AGENTS.md
Project overview
This is a model context protocol (MCP) server for the GWAS Catalog (https://ebi.ac.uk/gwas). The purpose of this repository is to enable natural language queries of data distributed via the GWAS Catalog REST API (v2, https://www.ebi.ac.uk/gwas/rest/api/v2/) by providing MCP tools, resources, and prompts.
The project is implemented using Python 3.13, MCP Python SDK v2.1.1, and Pydantic v2. uv is used for dependency management and nox is used for automation.
Environment setup
Requirements
- Python 3.13
- uv installed
Install dependencies
uv sync
Running the project
uv run gwas-mcp --transport http
Testing
nox is used to automate tests.
uv run nox -s tests
Linting and formatting
nox is used to automate linting and formatting.
uv run nox -s lint
To fix issues with the linter you might want to run the programs specified in the noxfile directly (e.g. ruff).

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.
