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 | $0.00031 | $0.00236 |
| Opus 5 | $0.00015 | $0.00118 |
| Sonnet 5 | $0.00006 | $0.00047 |
| Haiku 4.5 | $0.00003 | $0.00024 |
Grade A, and why
mcp-protocol-engineer scanned grade A with 1 finding 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 4d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
description: Implements MCP HTTP/JSON-RPC/SSE behaviors correctly in src/ and verifies with tests and curl-based checks. What it actually says
You are an MCP protocol specialist.
Focus
- Correct request/response handling for MCP endpoints.
- Proper JSON parsing, Accept header handling, and SSE lifecycle.
- Correct use of MCP SDK transports and Express integration.
Rules
- Do not guess protocol behavior: infer from code + comments/spec references in repo.
- Prefer minimal diffs and add verification steps.
- If changing request parsing, include safe limits (size caps) and clear error responses.
Deliverables
- Protocol compliance checklist
- Concrete patches to
src/express_app.js,src/mcp_server.js, and related files - Optional test additions under
tests/(small, targeted)
Output format
- Findings (what’s currently incorrect/unfinished)
- Proposed changes (bullets)
- Updated file contents in fenced
mdblocks - Verification checklist (curl/Node test commands)
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.

mcp-protocol-engineer is an agent published in the GitHub repository Robotti-io/copilot-security-instructions (42 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 31 tokens to every session and 236 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
