Implementation Reference

• src/rollbar.ts:445-461 (handler)

  Handler function that executes the rollbar_get_occurrence tool by calling the Rollbar API to fetch a specific occurrence by its ID using the projectClient.

  case "rollbar_get_occurrence": {
    // Project Token is required
    if (!projectClient) {
      throw new Error("ROLLBAR_PROJECT_TOKEN is not set, cannot use this API");
    }
  
    const { id } = args as { id: string };
    const response = await projectClient.get<OccurrenceResponse>(`/instance/${id}`);
    return {
      content: [
        {
          type: "text",
          text: JSON.stringify(response.data, null, 2),
        },
      ],
    };
  }

• src/rollbar.ts:192-202 (schema)

  Schema definition for the rollbar_get_occurrence tool, specifying the input parameters and description.

  const GET_OCCURRENCE_TOOL: Tool = {
    name: "rollbar_get_occurrence",
    description: "Get a specific occurrence of an error from Rollbar",
    inputSchema: {
      type: "object",
      properties: {
        id: { type: "string", description: "Occurrence ID" },
      },
      required: ["id"],
    },
  };

• src/rollbar.ts:298-314 (registration)

  Registration of the rollbar_get_occurrence tool (via GET_OCCURRENCE_TOOL) in the listTools request handler, making it available to clients.

  server.setRequestHandler(ListToolsRequestSchema, async () => ({
    tools: [
      LIST_ITEMS_TOOL,
      GET_ITEM_TOOL,
      GET_ITEM_BY_UUID_TOOL,
      GET_ITEM_BY_COUNTER_TOOL,
      LIST_OCCURRENCES_TOOL,
      GET_OCCURRENCE_TOOL,
      LIST_PROJECTS_TOOL,
      GET_PROJECT_TOOL,
      LIST_ENVIRONMENTS_TOOL,
      LIST_USERS_TOOL,
      GET_USER_TOOL,
      LIST_DEPLOYS_TOOL,
      GET_DEPLOY_TOOL,
    ],
  }));
