How do I connect Narsil MCP Server to Claude?

Run `claude mcp add narsil-mcp -- npx -y @modelcontextprotocol/inspector ./target/release/narsil-mcp --repos ./path/to/repo` in Claude Code, or add the same command and arguments under mcpServers in Cursor's mcp.json or Claude Desktop's claude_desktop_config.json, then restart the client. The blocks above are ready to paste.

Is Narsil MCP Server free?

The listed licence is Apache-2.0. Check the upstream terms for permitted use and commercial requirements; a public repository does not by itself mean the software is free or open source. Connected APIs and hosted services may have separate charges.

What can Narsil MCP Server do?

Narsil MCP Server documents 40 tools to the agent, including discover_repos, find_call_path, find_dead_code. The descriptions above come from project documentation. A live handshake does not test individual tool behavior.

01 / Choose your client

02 / Before you connect

Authentication is not specified. Check the project instructions before connecting.

Install the runtime required by the project and make it available to your client.

Project instructionsEnvironment variable names (optional)

Use names from the project instructions, separated by commas. Enter names only, never secret values.

03 / Add the configuration

Source: generated from public install instructions

claude mcp add --transport stdio 'narsil-mcp' -- 'npx' '-y' '@modelcontextprotocol/inspector' './target/release/narsil-mcp' '--repos' './path/to/repo'

Run in your terminal after replacing any placeholders.

04 / Check it in your client

Open your client’s MCP settings and confirm the server connects and lists its tools. A copied configuration does not confirm a working connection.
