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.

Add the following configuration:

{
  "mcpServers": {
    "skald": {
      "type": "command",
      "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

Open Claude Desktop settings and navigate to the "Developer" tab

Click "Edit Config"

Add the following configuration:

{
  "mcpServers": {
    "skald": {
      "command": "node",
      "args": [
        "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
YOUR_SKALD_API_KEY with your Skald API key

Environment variables:

SKALD_API_KEY: Your Skald API key (required)

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.
