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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00419 | $0.00419 |
| Opus 5 | $0.00210 | $0.00210 |
| Sonnet 5 | $0.00084 | $0.00084 |
| Haiku 4.5 | $0.00042 | $0.00042 |
Grade A, and why
github-pr-review-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 5d 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
GitHub PR Review MCP - Agent Instructions
MCP server providing GitHub PR review capabilities. Built with TypeScript, FastMCP, and GitHub API.
Quick Reference
| File | Purpose |
|---|---|
src/index.ts |
Register MCP tools |
src/github-service.ts |
GitHub API calls (use this.octokit) |
src/code-analyzer.ts |
Static analysis (pure functions) |
src/types.ts |
Zod schemas + TypeScript types |
Core Rules
- All GitHub API calls go through
GitHubService - All tool parameters need Zod schemas in
types.ts - Strong typing - avoid
any, use explicitinterfaceortypedefinitions - Use
?for optional - don't use| null | undefined, use?instead - Run
npm run validatebefore committing
Adding Tools (3 Steps)
- Schema in
types.ts - Service method in
github-service.ts - Register in
index.ts
Code Style
- 2 spaces, double quotes, semicolons
- kebab-case files, PascalCase classes, camelCase functions
- 80 char max line length
Commands
npm run validate # Type-check + lint + format
npm run dev # Development mode
npm run build # Production build
Error Handling
try {
const result = await this.octokit.pulls.get({...});
return result.data;
} catch (error) {
const message = error instanceof Error ? error.message : String(error);
console.error("Error fetching PR:", message);
throw new Error(`Failed to fetch PR: ${message}`);
}

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.
