Implementation Reference

• src/index.ts:787-821 (handler)

  Executes the unresolve_market tool: parses params with UnresolveMarketSchema, requires MANIFOLD_API_KEY, POSTs to Manifold /v0/unresolve endpoint, returns success message.

  case 'unresolve_market': {
    const params = UnresolveMarketSchema.parse(args);
    const apiKey = process.env.MANIFOLD_API_KEY;
    if (!apiKey) {
      throw new McpError(
        ErrorCode.InternalError,
        'MANIFOLD_API_KEY environment variable is required'
      );
    }
  
    const response = await fetch(`${API_BASE}/v0/unresolve`, {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json',
        Authorization: `Key ${apiKey}`,
      },
      body: JSON.stringify(params),
    });
  
    if (!response.ok) {
      throw new McpError(
        ErrorCode.InternalError,
        `Manifold API error: ${response.statusText}`
      );
    }
  
    return {
      content: [
        {
          type: 'text',
          text: 'Market unresolved successfully',
        },
      ],
    };
  }

• src/index.ts:92-95 (schema)

  Zod schema defining input for unresolve_market: contractId (string, required), answerId (string, optional).

  const UnresolveMarketSchema = z.object({
    contractId: z.string(),
    answerId: z.string().optional(),
  });
