Grav Cms MCP Connector

Overview

This skill enables Claude to interact with Grav Cms through the Model Context Protocol (MCP). It provides a bridge between Claude's AI capabilities and Grav Cms's CLI/File-based, allowing natural language control of Grav Cms operations, intelligent automation, and AI-powered assistance for Grav Cms workflows.

When to Use This Skill

• Page creation and frontmatter configuration
• Theme and blueprint customization
• Plugin configuration and management
• Twig template generation with AI
• Multi-language content management

Core Concepts

MCP Server Setup

The connector implements an MCP server that exposes Grav Cms operations as tools Claude can invoke. The server translates natural language intentions into CLI/File-based calls.

Key Endpoints/Interfaces

grav pages, grav backup, grav install, grav cache, grav composer

Implementation

// Grav Cms MCP Server Implementation
import { McpServer } from "@modelcontextprotocol/sdk/server/mcp.js";
import { StdioServerTransport } from "@modelcontextprotocol/sdk/server/stdio.js";
import { z } from "zod";

const server = new McpServer({
  name: "grav-cms-mcp-connector",
  version: "1.0.0",
});

// Tool: List/Query Resources
server.tool(
  "list_resources",
  "List and query Grav Cms resources with optional filters",
  {
    query: z.string().optional().describe("Search query or filter"),
    limit: z.number().optional().describe("Max results to return"),
  },
  async ({ query, limit }) => {
    // Call Grav Cms CLI/File-based
    const response = await fetch(`${BASE_URL}grav pages`, {
      headers: { "Authorization": `Bearer ${API_KEY}` },
    });
    const data = await response.json();
    return {
      : [{ : , : .(data, , ) }],
    };
  }
);


server.(
  ,
  ,
  {
    : z.().(),
    : z.({}).().().(),
  },
   ({ name, config }) => {
     response =  (, {
      : ,
      : {
        : ,
        : ,
      },
      : .({ name, ...config }),
    });
     data =  response.();
     {
      : [{ : , :  }],
    };
  }
);


server.(
  ,
  ,
  {
    : z.().(),
    : z.().().(),
  },
   ({ , timeframe }) => {
    
     response =  (, {
      : { :  },
    });
     data =  response.();
     {
      : [{ : , : .(data, , ) }],
    };
  }
);


 transport =  ();
 server.(transport);

Best Practices

1. Authentication: Store API keys securely using environment variables; never hardcode credentials
2. Rate Limiting: Implement request throttling to respect Grav Cms API rate limits
3. Error Handling: Provide clear, actionable error messages for common failure scenarios
4. Pagination: Handle paginated responses for large datasets efficiently
5. Caching: Cache frequently accessed read-only data to reduce API calls
6. Security: Validate all inputs before passing to the Grav Cms API; sanitize outputs
7. Logging: Log all API interactions for debugging and audit purposes

Example Prompts

"Create a documentation site structure with sidebar navigation and search functionality"

Security Considerations

• All API credentials must be stored as environment variables
• Implement input validation and sanitization for all tool parameters
• Use HTTPS for all API communications
• Follow the principle of least privilege for API token permissions
• Audit log all write operations for compliance tracking
