Implementation Reference

• src/index.ts:1377-1396 (handler)

  Tool handler that extracts parameters, calls SentryAPIClient.searchErrorsInFile, and formats the response.

  case "sentry_search_errors_in_file": {
    if (!apiClient) {
      throw new Error("Sentry API client not initialized. Provide auth token.");
    }
    
    const { projectSlug, filename } = args as any;
    const issues = await apiClient.searchErrorsInFile(projectSlug, filename);
    
    return {
      content: [
        {
          type: "text",
          text: `Found ${issues.length} issues in file ${filename}:\n` +
            issues.map((i: any) => 
              `- ${i.shortId}: ${i.title} (${i.count} events, ${i.userCount} users)`
            ).join('\n'),
        },
      ],
    };
  }

• src/index.ts:671-688 (schema)

  Tool schema definition including input schema and description, registered in listTools response.

  {
    name: "sentry_search_errors_in_file",
    description: "Search for Sentry errors occurring in a specific file. Find all issues related to a particular file path or filename.",
    inputSchema: {
      type: "object",
      properties: {
        projectSlug: {
          type: "string",
          description: "Project slug/identifier",
        },
        filename: {
          type: "string",
          description: "File path or filename to search for",
        },
      },
      required: ["projectSlug", "filename"],
    },
  },

• src/sentry-api-client.ts:201-204 (helper)

  Core helper method in SentryAPIClient that constructs a filename query and delegates to listIssues.

  async searchErrorsInFile(projectSlug: string, filename: string) {
    const query = `filename:"${filename}"`;
    return this.listIssues(projectSlug, query);
  }
