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 | $0.00000 | $0.00923 |
| Opus 5 | $0.00000 | $0.00462 |
| Sonnet 5 | $0.00000 | $0.00185 |
| Haiku 4.5 | $0.00000 | $0.00092 |
Grade A, and why
mcp-research 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 9d 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
100% identical to mcp-research — 0 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
The opening of the file, as written. The whole thing — 117 lines — stays where its author put it; the contents beside it link to each section on GitHub.
name: mcp-research description: Expert research tool for Model Context Protocol implementations. PROACTIVELY use when reviewing MCP server code, planning new MCP tools/resources/prompts, investigating protocol compliance issues, or validating architecture. Specializes in protocol compliance (JSON-RPC 2.0), security patterns, transport layers, and production best practices. Current spec: 2025-06-18. allowed-tools: Read, Grep, Glob, WebFetch, WebSearch
MCP Implementation Research
Quick Start
What are you doing?
- 📝 Reviewing MCP server →
references/implementation-checklist.md - 🚀 Planning MCP feature →
references/protocol-patterns.md - 🐛 Protocol issue →
references/common-pitfalls.md - ✅ Architecture validation → All references + latest spec
Research Workflow
- Understand implementation - What MCP capabilities? Which transport? What security requirements?
- Consult references - Load relevant reference files progressively
- Check latest spec - WebFetch
https://modelcontextprotocol.io/specification/2025-06-18 - Search community - WebSearch for "MCP [specific-issue] 2025"
- Validate compliance - Protocol compliance, security, best practices
- Report findings - Structured format (see examples/)
Critical MCP Requirements
Protocol Compliance (JSON-RPC 2.0)
- All messages MUST include
jsonrpc: "2.0" - Responses include
resultORerror, never both - Initialization:
initialize→ response →initializednotification - Use standard error codes (-32xxx)
Security & Consent
- User consent MUST be obtained before data access
- Tool execution requires explicit approval
- No hardcoded credentials
- Input/output sanitization required
Capability Advertisement
- Declare all capabilities in
initializeresponse - Types:
tools,resources,prompts,logging,experimental - Protocol version:
"2025-06-18"(latest)
Transport Layers
stdio:
- Newline-delimited JSON-RPC messages
- Use stderr for logging (not stdout)
- Flush after each message
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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-research is a skill published in the GitHub repository QuantGeekDev/google-calendar-mcp-app (3 stars, last pushed 5mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 923 tokens. A static security scan graded it A with 0 findings. It is 100% identical to mcp-research, differing in 0 lines, and is treated as a copy.
