Adding New Tools
Tools extend the MCP server functionality with custom operations. Follow these steps:
-
Choose a meaningful tool name (e.g.,
analyze_code
,generate_tests
,check_dependencies
) -
Create the tool definition in
public/tools/your-tool.json
:{ "id": "analyze_code_complexity", "name": "analyze_code_complexity", "description": "Analyze code complexity and suggest improvements", "input_schema": { "type": "object", "properties": { "code": { "type": "string", "description": "The code to analyze" }, "language": { "type": "string", "description": "Programming language (js, ts, py, etc.)" }, "metrics": { "type": "array", "items": { "type": "string" }, "description": "Metrics to calculate (cyclomatic, cognitive, etc.)" } }, "required": ["code", "language"] } }
-
Implement the tool logic in
src/server.ts
CallToolRequestSchema handler:case "analyze_code_complexity": if (!args || typeof args.code !== "string") { throw new McpError(ErrorCode.InvalidRequest, "Code parameter is required"); } const analysis = await this.analyzeCodeComplexity(args.code, args.language); return { content: [ { type: "text", text: JSON.stringify(analysis, null, 2) } ] };
-
Test the tool with MCP Inspector and various inputs
Tool Ideas:
validate_env_vars
: Check environment variable completenessgenerate_tests
: Create unit tests for given codecheck_dependencies
: Analyze package.json for vulnerabilitiesformat_sql
: Format and validate SQL queriesanalyze_performance
: Detect performance bottlenecksgenerate_docs
: Create documentation from code comments
๐ Quality Standards
All prompts must meet these criteria:
- Effectiveness: Average rating of 4.0+ from community testing
