💬 Ask Questions	Natural-language Q&A with conversation history
🧠 NLP Repo Resolution	Type naturally — wink-nlp extracts keywords and resolves to `owner/repo`
📡 Multiple Transports	stdio (default), Streamable HTTP, SSE
🔄 Retry with Backoff	Automatic retries with exponential backoff on 5xx errors
🐳 Docker Support	Multi-stage Alpine build
📊 Response Metadata	Byte count and elapsed time on every response

🚀 Quick Start

Using npx (no install)

npx -y codewiki-mcp@latest

From source

git clone https://github.com/izzzzzi/codewiki-mcp.git

⚙️ How It Works

Data Flow

AI Assistant → MCP protocol → codewiki-mcp → HTTPS → codewiki.google
                                                            ↓
AI Assistant ← MCP protocol ← codewiki-mcp ← JSON  ← Google RPC API

Google Batchexecute RPC

codewiki.google uses Google's internal batchexecute RPC format (not REST, not GraphQL). The client:

Builds a POST request with f.req=... body
Sends it to /_/BoqAngularSdlcAgentsUi/data/batchexecute
Receives a response with XSSI prefix )]}'\n
Parses wrb.fr frames and extracts the typed payload

Each tool maps to an RPC ID:

Tool	RPC ID
🔍 Search	`vyWDAf`
📄 Fetch	`VSX6ub`
💬 Ask	`EgIxfe`

🧠 NLP Repo Resolution

Users can type natural language instead of owner/repo:

"the fastify web framework"
  → wink-nlp extracts keyword "fastify" (POS tag: NOUN/PROPN)
  → GitHub Search API: GET /search/repositories?q=fastify&sort=stars
  → top result: "fastify/fastify"
  → normalizeRepoInput("fastify/fastify") → URL for codewiki

🔄 Retry with Exponential Backoff

Attempt	Delay
0	immediate
1	250ms
2	500ms
3	1000ms

4xx errors (client errors) are never retried.

🖥️ CLI

codewiki-mcp [options]

Options:
  --http           Streamable HTTP transport
  --sse            SSE transport
  --port <number>  Port for HTTP/SSE (default: 3000)
  --endpoint <str> URL endpoint (default: /mcp)
  --help, -h       Show help

⚡ Configuration

Environment variables:

Variable	Default	Description
`CODEWIKI_BASE_URL`	`https://codewiki.google`	Base URL
`CODEWIKI_REQUEST_TIMEOUT`	`30000`	Request timeout (ms)
`CODEWIKI_MAX_RETRIES`	`3`	Max retries
`CODEWIKI_RETRY_DELAY`	`250`	Base retry delay (ms)
`GITHUB_TOKEN`	—	GitHub token for NLP repo resolution

You can also create a .env file in the project root:

CODEWIKI_REQUEST_TIMEOUT=60000
CODEWIKI_MAX_RETRIES=5
GITHUB_TOKEN=ghp_your_token

❓ Troubleshooting

chmod +x ./node_modules/.bin/codewiki-mcp

# Check if port is in use
lsof -i :3000

For large repositories, increase the timeout:

CODEWIKI_REQUEST_TIMEOUT=60000 node dist/cli.js

If natural-language input doesn't resolve, use explicit format:

# Instead of "the fastify framework"
fastify/fastify
# or
https://github.com/fastify/fastify

Set GITHUB_TOKEN to avoid GitHub API rate limits for unauthenticated requests.
