Anti-Bullshit MCP Server

Instructions

Implementation Reference

• src/index.ts:253-315 (handler)

  The core handler logic for the 'check_manipulation' tool. It uses regex patterns to detect manipulation tactics (emotional appeals, social proof, false authority, scarcity) in the input text and generates customized validation prompts recommending searches across MCP tools like Exa, Brave, ArXiv, and Google Scholar.
  if (name === "check_manipulation") { const patterns = { emotional: /fear|urgent|must act|limited time|don't wait|before it's too late/i, social: /everyone knows|nobody wants|you don't want to be|don't miss out/i, authority: /experts say|scientists claim|studies show|research proves/i, scarcity: /limited time|exclusive|rare opportunity|don't miss out/i }; const detectedPatterns = Object.entries(patterns) .filter(([_, pattern]) => pattern.test(args.text)) .map(([type]) => type); // Generate validation prompts const validationPrompts = [ `- Use Exa MCP server to search for factual information: "${args.text}"`, `- Use Brave Search for independent fact-checking: "${args.text}"`, `- Search ArXiv for technical analysis: "${args.text}"`, `- Use Google Scholar MCP server to find peer-reviewed research: "${args.text}"`, `- Cross-reference findings across different platforms to establish truth` ]; if (detectedPatterns.includes("authority")) { validationPrompts.push( `- Use Google Scholar MCP server to verify credibility of cited authorities`, `- Cross-reference authority claims with independent research`, `- Compare expert opinions across different fields` ); } if (detectedPatterns.includes("emotional")) { validationPrompts.push( `- Use Exa MCP server to find balanced, non-emotional discussions`, `- Compare emotional appeals with empirical evidence`, `- Cross-validate claims across multiple neutral sources` ); } if (detectedPatterns.includes("social") || detectedPatterns.includes("scarcity")) { validationPrompts.push( `- Verify claims using multiple independent sources`, `- Cross-reference marketing claims with factual data`, `- Compare urgency claims with historical patterns` ); } return { content: [ { type: "text", text: `Manipulation check results:\n\n` + `Detected patterns: ${detectedPatterns.join(", ") || "None"}\n\n` + `Suggested validation:\n${validationPrompts.join("\n")}` }, { type: "text", text: JSON.stringify({ detectedPatterns, validationPrompts }, null, 2) } ], }; }
• src/index.ts:73-86 (schema)

  Tool registration in ListTools response, including name, description, and input schema definition requiring a 'text' string parameter.
  { name: "check_manipulation", description: "Check for manipulation tactics across different cultural contexts", inputSchema: { type: "object", properties: { text: { type: "string", description: "Text to analyze for manipulation", } }, required: ["text"], }, }
• src/index.ts:22-22 (registration)

  Capability declaration enabling the 'check_manipulation' tool in the MCP server configuration.
  check_manipulation: true
• src/index.ts:32-89 (registration)

  Registration of the ListTools handler that exposes the 'check_manipulation' tool details including schema.
  server.setRequestHandler(ListToolsRequestSchema, async () => { return { tools: [ { name: "analyze_claim", description: "Analyze a claim using multiple epistemological frameworks and suggest validation steps", inputSchema: { type: "object", properties: { text: { type: "string", description: "Claim to analyze", }, framework: { type: "string", description: "Validation framework to use (empirical, responsible, harmonic, or pluralistic)", enum: ["empirical", "responsible", "harmonic", "pluralistic"], } }, required: ["text"], }, }, { name: "validate_sources", description: "Validate sources and evidence using configured framework", inputSchema: { type: "object", properties: { text: { type: "string", description: "Text containing claims and sources to validate", }, framework: { type: "string", description: "Validation framework to use", enum: ["empirical", "responsible", "harmonic", "pluralistic"], } }, required: ["text"], }, }, { name: "check_manipulation", description: "Check for manipulation tactics across different cultural contexts", inputSchema: { type: "object", properties: { text: { type: "string", description: "Text to analyze for manipulation", } }, required: ["text"], }, } ], }; });
• src/index.ts:97-327 (registration)

  Registration of the CallTool handler that dispatches to the specific check_manipulation implementation.
