Docs

Generic MCP server that exposes Markdown documentation to LLMs, enabling them to search and answer questions about any software documentation.

The server identity (name, instructions, category labels) is driven entirely by the docs/ directory — which is a separate repository cloned alongside this one.

Requirements

• Python 3.14+
• uv

Setup

1. Clone the documentation repository

The docs/ directory must exist before the server can start. Clone the documentation repository into it:

git clone <docs-repo-url> docs

2. Install dependencies

uv sync

3. Configure environment variables (optional)

Copy .env.example to .env and set MCP_DOCS_DIR if your documentation directory lives outside docs/:

cp .env.example .env

Variable	Default	Description
MCP_DOCS_DIR	./docs	Absolute or relative path to the documentation directory

docs/ directory structure

The server auto-discovers categories from subdirectories. The only required file is config.toml at the root of docs/.

docs/
├── config.toml          # required — project identity
├── <category>/
│   ├── <topic>.md
│   └── ...
└── <category>/
    └── ...

config.toml

[project]
name = "my-project"
instructions = """
System instructions for the LLM. Describe what this documentation covers
and how the model should use the available tools.
"""

[categories]
folder-name = "Human-readable label"

• [project] is required. name identifies the server; instructions guides the LLM.
• [categories] is optional. Any subdirectory not listed gets a title-cased label automatically (my-folder → My Folder).
• Files inside img/ subdirectories are never served.

Usage

Run the server (stdio mode)

uv run main.py

Development with MCP Inspector

uv run mcp dev main.py

Opens the MCP Inspector in the browser. To connect to a running SSE or Streamable HTTP server, start it first and point the inspector to the printed endpoint:

uv run main.py --transport sse
uv run main.py --transport streamable-http

Configure with Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "my-project": {
      "command": "uv",
      "args": ["--directory", "/path/to/mcp-docs", "run", "main.py"],
      "env": { "MCP_DOCS_DIR": "/path/to/your/docs" }
    }
  }
}

Configure with Claude Code

claude mcp add my-project -- uv --directory /path/to/mcp-docs run main.py

To pass MCP_DOCS_DIR when using Claude Code, add it to the server environment:

claude mcp add my-project -e MCP_DOCS_DIR=/path/to/your/docs -- uv --directory /path/to/mcp-docs run main.py

Containers

Build da imagem

# Docker
docker build -f .containers/Dockerfile -t mcp-docs:latest .

# Podman
podman build -f .containers/Dockerfile -t mcp-docs:latest .

Executar localmente com docker-compose

Certifique-se de que o diretório docs/ existe e está populado antes de iniciar:

docker compose up

# ou com Podman
podman compose up

O servidor ficará disponível em http://localhost:8080/mcp.

Executar o container manualmente

# Docker
docker run --rm -p 8080:8080 -v ./docs:/docs:ro mcp-docs:latest

# Podman
podman run --rm -p 8080:8080 -v ./docs:/docs:ro mcp-docs:latest

Deploy no Kubernetes

Os arquivos de deployment e service estão em .containers/. Edite image: em deployment.yaml para apontar para o seu registry antes de aplicar.

kubectl apply -f .containers/deployment.yaml
kubectl apply -f .containers/service.yaml

O Deployment referencia um PersistentVolumeClaim chamado mcp-docs-pvc para montar os arquivos de documentação em /docs. Crie e popule o PVC com a documentação antes de aplicar o Deployment.

Testando com o MCP Inspector

Com o container rodando localmente (via docker compose up ou manualmente), o endpoint Streamable HTTP estará em http://localhost:8080/mcp.

1. Abra o MCP Inspector:

   npx @modelcontextprotocol/inspector
   

2. No inspector, selecione o transport Streamable HTTP.

3. Informe a URL: http://localhost:8080/mcp

4. Clique em Connect.

5. Teste as ferramentas disponíveis: list_docs, read_doc, search_docs.
