MCP-Kanka

MCP (Model Context Protocol) server for Kanka API integration. This server provides AI assistants with tools to interact with Kanka campaigns, enabling CRUD operations on various entity types like characters, locations, organizations, and more.

This package is designed specifically to serve the needs of Teghrim but may be useful to others working with Kanka and MCP.

Search & Filtering

The MCP server provides enhanced search capabilities:

• Content search: Full-text search across entity names and content (client-side)
• Name filter: Exact or fuzzy name matching
• Type filter: Filter by user-defined type field (e.g., 'NPC', 'City')
• Tag filter: Filter by tags (AND logic - entity must have all specified tags)
• Date range: Filter journals by date
• Fuzzy matching: Optional fuzzy name matching for more flexible searches
• Last sync filter: Use Kanka's native lastSync parameter to get only modified entities

Note: Content search fetches all entities and searches client-side, which may be slower for large campaigns but provides comprehensive search functionality.

Synchronization Features

Timestamp Support

All entities include created_at and updated_at timestamps in ISO 8601 format, enabling:

• Tracking when entities were created or last modified
• Implementing conflict resolution strategies
• Building audit trails

Sync Metadata

The find_entities tool returns sync metadata including:

• request_timestamp: When the request was made
• newest_updated_at: Latest updated_at from returned entities
• total_count: Total matching entities
• returned_count: Number returned in this response

Efficient Sync with lastSync

Use the last_synced parameter to fetch only entities modified after a specific time:

# Example: Get entities modified in the last 24 hours
result = await find_entities(
    entity_type="character",
    last_synced="2024-01-01T00:00:00Z"
)

Batch Update Checking

The check_entity_updates tool efficiently checks which entities have been modified:

# Check which of these entities have changed
result = await check_entity_updates(
    entity_ids=[101, 102, 103],
    last_synced="2024-01-01T00:00:00Z"
)
# Returns: modified_entity_ids, deleted_entity_ids, check_timestamp

Programmatic Usage

In addition to being an MCP server, this package provides an operations layer that can be used directly in Python scripts:

from mcp_kanka.operations import create_operations

# Create operations instance
ops = create_operations()

# Find entities
result = await ops.find_entities(
    entity_type="character",
    name="Moradin"
)

# Create an entity
results = await ops.create_entities([{
    "entity_type": "character",
    "name": "New Character",
    "type": "NPC",
    "entry": "A mysterious figure"
}])

This makes it easy to build sync scripts, bulk operations, or other tools that interact with Kanka.

The MCP server requires:

• KANKA_TOKEN: Your Kanka API token
