Skald MCP Server 🧠

Chat with your Skald knowledge base, add and update new knowledge, and search through memos.

Features

The Skald MCP server provides seven powerful tools:

1. skald-chat

Ask Skald questions about your knowledge base in natural language with optional filters to narrow search context.

2. skald-search

Search through your memos using multiple methods with optional filters:

• Semantic search (chunk_vector_search) - Find relevant content by meaning
• Title contains (title_contains) - Case-insensitive substring matching
• Title starts with (title_startswith) - Case-insensitive prefix matching

3. skald-create-memo

Create new memos that are automatically processed, summarized, tagged, chunked, and indexed for search.

4. skald-get-memo

Retrieve a memo by UUID or client reference ID with full content, summary, tags, and chunks.

5. skald-update-memo

Update an existing memo by UUID or client reference ID. If content is updated, the memo will be reprocessed.

6. skald-delete-memo

Permanently delete a memo by UUID or client reference ID along with all associated data.

7. skald-generate

Generate documents based on prompts and retrieved context from the knowledge base with optional style/format rules and filters.

      "command": "node ABSOLUTE_PATH_TO_PROJECT/build/index.js --key=YOUR_SKALD_API_KEY"
    }
  }
}

Replace:

• ABSOLUTE_PATH_TO_PROJECT with the full path to your skald-mcp directory
• YOUR_SKALD_API_KEY with your Skald API key

Tip: Right-click on /build/index.js in Cursor and select "Copy Path" to get the absolute path.

Command-line arguments:

• --key: Your Skald API key (required if not using environment variable)

Claude Desktop

  "mcpServers": {
    "skald": {
      "command": "node",

        "ABSOLUTE_PATH_TO_PROJECT/build/index.js"
      ],
      "env": {
        "SKALD_API_KEY": "YOUR_SKALD_API_KEY"
      }
    }
  }
}

Replace:

• ABSOLUTE_PATH_TO_PROJECT with the full path to your skald-mcp directory

Environment variables:

• SKALD_API_KEY: Your Skald API key (required)

4. Restart Claude Desktop

Usage Examples

Chat with your knowledge base

Ask Cursor/Claude: "Check Skald for what are the instructions for running our Django server locally."

The assistant will query your Skald knowledge base and return an answer.

Search for memos

Ask Cursor/Claude: "Search Skald for the docs about our product vision"

The assistant will use the skald-search tool with semantic search to find relevant memos and display:

• Title
• UUID
• Summary
• Content snippet
• Relevance score (for semantic search)

If you had asked for "memos with Product Vision in the title", the agent would pick another search method such as title_contains.

Create a new memo

Ask Cursor/Claude: "Generate an API reference for my endpoints and upload it to Skald"

The assistant will create a new memo in your Skald knowledge base, which will be automatically processed and made searchable.
