Implementation Reference

  • Handler for 'rollbar_get_item' tool: validates project token, extracts item ID from arguments, fetches item data from Rollbar API endpoint '/item/{id}', and returns JSON response.
    case "rollbar_get_item": {
      // Project Token is required
      if (!projectClient) {
        throw new Error("ROLLBAR_PROJECT_TOKEN is not set, cannot use this API");
      }
    
      const { id } = args as { id: number };
      const response = await projectClient.get<ItemResponse>(`/item/${id}`);
      return {
        content: [
          {
            type: "text",
            text: JSON.stringify(response.data, null, 2),
          },
        ],
      };
    }
  • Schema definition for 'rollbar_get_item' tool, specifying input requirements: object with required 'id' property of type number.
    const GET_ITEM_TOOL: Tool = {
      name: "rollbar_get_item",
      description: "Get a specific item (error) from Rollbar using the internal item ID maintained by Rollbar's system.",
      inputSchema: {
        type: "object",
        properties: {
          id: { type: "number", description: "Item ID" },
        },
        required: ["id"],
      },
    };
  • src/rollbar.ts:298-314 (registration)
    Registration of 'rollbar_get_item' tool (as GET_ITEM_TOOL) in the listTools response handler, making it discoverable by MCP 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,
      ],
    }));
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries full burden. It states this is a 'Get' operation which implies read-only, but doesn't disclose behavioral traits like authentication requirements, rate limits, error handling, or what data is returned. For a tool with zero annotation coverage, this leaves significant gaps in understanding how the tool behaves.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, well-structured sentence that efficiently communicates the tool's purpose and key constraint. Every word earns its place with no redundancy or unnecessary elaboration.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool has 1 parameter with 100% schema coverage but no annotations and no output schema, the description provides adequate basic information about what the tool does. However, for a read operation that likely returns complex error data, the description doesn't explain what information is returned or any behavioral constraints, leaving room for improvement.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% with the single parameter 'id' fully documented as 'Item ID'. The description adds that this is 'the internal item ID maintained by Rollbar's system', providing useful context about what type of ID this is. This matches the baseline score when schema coverage is high.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'Get' and resource 'specific item (error) from Rollbar', specifying it uses the internal item ID. It distinguishes from siblings like rollbar_list_items (list vs get) but doesn't explicitly differentiate from rollbar_get_item_by_counter or rollbar_get_item_by_occurrence_uuid which use different identifiers.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage context by specifying 'using the internal item ID maintained by Rollbar's system', suggesting this is for when you have the internal ID rather than other identifiers. However, it doesn't explicitly state when to use this versus alternatives like rollbar_get_item_by_counter or rollbar_get_item_by_occurrence_uuid, nor does it mention prerequisites or exclusions.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
