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.

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 | $0.00068 | $0.00830 |
| Opus 5 | $0.00034 | $0.00415 |
| Sonnet 5 | $0.00014 | $0.00166 |
| Haiku 4.5 | $0.00007 | $0.00083 |
Grade A, and why
github-to-mcp-guide 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 yesterday.
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.
How it starts
The opening of the file, as written. The whole thing — 114 lines — stays where its author put it; the contents beside it link to each section on GitHub.
GitHub-to-MCP Conversion Guide
Convert any GitHub repository into an MCP server automatically. The tool analyzes the repo's API surface (OpenAPI specs, GraphQL schemas, REST endpoints) and generates a working MCP server with type-safe tools.
How It Works
GitHub Repo URL
│
▼
1. Clone & analyze repo
│

2. Detect API surface
├── OpenAPI/Swagger specs
├── GraphQL schemas
├── REST route definitions
└── Function exports
│

3. Generate MCP server
├── TypeScript or Python
├── Type-safe tool definitions
├── Parameter validation
└── Error handling
│

4. Ready-to-use MCP server
Quick Start
npx github-to-mcp https://github.com/owner/repo
This generates a ready-to-use MCP server in ./mcp-output/.
Supported API Formats
| Format | Detection | Example |
|---|---|---|
| OpenAPI 3.x | openapi.json, swagger.yaml |
REST APIs with full schema |
| GraphQL | schema.graphql, introspection |
Query/mutation → tools |
| Express/Fastify | Route scanning | app.get('/api/...') → tools |
| Next.js API | Route file detection | app/api/*/route.ts → tools |
| Function exports | Named export analysis | export function doThing() → tools |
Output Options
TypeScript MCP Server
github-to-mcp https://github.com/owner/repo --lang typescript
Generates a Node.js MCP server with full TypeScript types.
Python MCP Server
github-to-mcp https://github.com/owner/repo --lang python
Generates a Python MCP server using the official MCP SDK.
AI-Powered Generation
When the API surface is ambiguous, the tool uses AI (GPT-4 or Claude) to:
- Infer parameter types from usage patterns
- Generate meaningful tool descriptions
- Create example inputs for each tool
- Handle edge cases in API design
Use Cases
Turn a DeFi Protocol into MCP Tools
github-to-mcp https://github.com/aave/aave-v3-core
# → Generates MCP tools for supply, borrow, repay, liquidate, etc.
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.
- yesterday First seen · 114 lines · 68 tokens per session scan A add2eda174e9
github-to-mcp-guide is a skill published in the GitHub repository nirholas/three.ws (110 stars, last pushed yesterday), licensed Apache-2.0. It adds 68 tokens to every session and 830 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
