How to Set Up and Use Yargı
Yargı MCP is a FastMCP server that gives AI models structured access to 15 Turkish legal institutions through 24 specialized tools, covering courts ranging from the Supreme Court (Yargıtay) and Council of State (Danıştay) to the Constitutional Court, Court of Accounts, competition authority, and data protection authority (KVKK). It enables semantic and keyword search across case law, tax directives, insurance arbitration decisions, and more, with full document retrieval in paginated Markdown. Legal researchers, law students, and Turkish legal professionals use it to have Claude search and summarize authoritative court decisions in natural language.
Prerequisites
- Python 3.10+ and uv package manager (or pip) installed
- An MCP-compatible client such as Claude Desktop, 5ire, or Gemini CLI
- Optional: an OpenRouter API key (OPENROUTER_API_KEY) for hosted semantic embeddings, or a local embedding model endpoint
Install uvx (if not already installed)
Yargı MCP is published to PyPI and can be run directly with uvx, which handles the virtual environment automatically. Install uv first if you do not have it.
curl -LsSf https://astral.sh/uv/install.sh | shTest the server locally
Run yargi-mcp directly with uvx to verify it starts without errors. You should see the FastMCP server start message.
uvx yargi-mcpConfigure your MCP client
Add yargi-mcp to your MCP client configuration file. The basic setup requires no environment variables — semantic search is optional and uses public court APIs by default.
{
"mcpServers": {
"Yargı MCP": {
"command": "uvx",
"args": ["yargi-mcp"]
}
}
}(Optional) Enable semantic search with embeddings
For richer semantic similarity search, add an OpenRouter API key or configure a local embedding endpoint via environment variables in your client config.
{
"mcpServers": {
"Yargı MCP": {
"command": "uvx",
"args": ["yargi-mcp"],
"env": {
"OPENROUTER_API_KEY": "sk-or-..."
}
}
}
}Alternatively, use the hosted remote MCP endpoint
No installation needed — connect directly to the hosted endpoint for zero-setup access to all Turkish legal databases.

Client configuration (Claude Desktop, local uvx)
Minimal configuration for Claude Desktop using uvx to run yargi-mcp with no extra dependencies:
{
"mcpServers": {
"Yargı MCP": {
"command": "uvx",
"args": ["yargi-mcp"]
}
}
}Prompts to try
Use natural language to search Turkish legal databases:
- "Search Supreme Court decisions about wrongful termination from 2023 in the labor law chamber"
- "Find Constitutional Court individual petition decisions related to freedom of expression"
- "Look up KVKK (data protection authority) decisions about cookie consent violations"
- "Search tax directives (özelge) about VAT exemptions for software exports"
- "Find competition authority decisions involving abuse of dominant position in the telecom sector"Troubleshooting Yargı
uvx command not found
Install the uv package manager using: curl -LsSf https://astral.sh/uv/install.sh | sh, then restart your terminal. Alternatively, install with pip: pip install uv.
Semantic search returns no results even with OPENROUTER_API_KEY set
Verify the API key is valid and has credits. You can also switch to keyword-only search by omitting the embedding config — most tools support phrase and date-range filtering without embeddings.
Document retrieval returns truncated content
The get_*_document_markdown tools paginate output in 5,000-character pages. Ask the AI to fetch the next page (e.g., 'get page 2 of that decision') to retrieve the full document.
