Implementation Reference
- src/index.ts:175-251 (handler)Main execution logic for the validate_sources tool: parses framework, extracts potential sources via regex matching phrases like 'according to', generates framework-specific validation prompts using external MCP servers (Exa, Brave, ArXiv, Google Scholar), and returns text summary and JSON with sources and prompts.if (name === "validate_sources") { const framework: keyof typeof VALIDATION_FRAMEWORKS = (typeof args.framework === 'string' && args.framework in VALIDATION_FRAMEWORKS) ? args.framework as keyof typeof VALIDATION_FRAMEWORKS : VALIDATION_FRAMEWORK; // Extract sources const sourcePattern = /according to|cited by|reported by|study by|research by|experts|scientists/gi; const sources = []; let match: RegExpExecArray | null; while ((match = sourcePattern.exec(args.text)) !== null) { const context = args.text.substring( Math.max(0, match.index - 30), Math.min(args.text.length, match.index + 70) ); sources.push({ type: "citation", context: context.trim() }); } // Generate validation prompts for each source const validationPrompts = sources.flatMap((source: { type: string; context: string }) => { const basePrompts = [ `- Use Exa MCP server to verify credibility of: "${source.context}"`, `- Use Brave Search to find independent verification: "${source.context}"`, `- Search ArXiv for related technical papers: "${source.context}"`, `- Use Google Scholar MCP server to check academic citations: "${source.context}"`, `- Cross-reference findings between different platforms to establish credibility` ]; if (framework === "empirical" || framework === "pluralistic") { basePrompts.push( `- Compare methodologies and results across different studies`, `- Verify replication status and reproducibility`, `- Cross-validate findings between different research groups` ); } if (framework === "responsible" || framework === "pluralistic") { basePrompts.push( `- Use Exa MCP server to search for community perspectives: "${source.context}"`, `- Compare academic findings with real-world impacts`, `- Cross-reference with local knowledge and experiences` ); } if (framework === "harmonic" || framework === "pluralistic") { basePrompts.push( `- Compare perspectives across different cultural contexts`, `- Synthesize findings from multiple knowledge systems`, `- Identify areas of consensus and divergence` ); } return basePrompts; }); return { content: [ { type: "text", text: `Source validation using ${framework} framework:\n\n` + `Found ${sources.length} sources to validate.\n\n` + `Validation steps:\n${validationPrompts.join("\n")}` }, { type: "text", text: JSON.stringify({ framework, sources, validationPrompts }, null, 2) } ], }; }
