CCDV-F Tools and MCP Integration — Timed 10 Questions

Question 1

When designing an MCP Server to help Claude interact with a local database, a developer needs to decide between using MCP Resources or MCP Tools. Which TWO statements correctly describe the differences between these primitives?

10 minute time limit — choose an answer to begin.

Accepted Answer

Resources are intended for read-only data that Claude can use as context.. Choosing the right MCP primitive is essential for optimal model performance. Resources are passive data sources that Claude can read for context, similar to documentation or files. Tools are active components that allow the model to perform actions or execute code. Distinguishing between data retrieval and action execution ensures that the model uses the most efficient path for information.

Answer

Resources require a JSON schema for input arguments just like tools do.

Answer

Tools are automatically called by the MCP Host without model intervention.

Answer

Resources are always updated in real-time via a WebSocket push mechanism.

Question 2

A developer wants to ensure that Claude uses a specific 'search_documentation' tool every single time a user asks a question about their proprietary software. Which configuration of the 'tool_choice' parameter should be used?

Accepted Answer

Set tool_choice to {'type': 'tool', 'name': 'search_documentation'}.. The 'tool_choice' parameter allows developers to control Claude's tool-calling behavior. By default, 'auto' lets Claude decide if a tool is needed. Setting 'tool_choice' to 'tool' with a specific name forces Claude to use that tool for its next response, regardless of whether it thinks it needs it, which is ideal for rigid workflows.

Answer

Set tool_choice to 'auto' and include the instruction in the system prompt.

Answer

Set tool_choice to 'any' to allow Claude to pick any available tool.

Answer

Omit the tool_choice parameter entirely as it defaults to 'required'.

Question 3

A developer is building a complex MCP-based system. They want to utilize 'MCP Prompts' to standardize how Claude interacts with their server. Which THREE statements accurately describe the capabilities and behavior of MCP Prompts?

Accepted Answer

They allow servers to expose reusable templates with variable arguments.. MCP Prompts are a powerful feature that allows servers to provide predefined templates for the model. They help standardize interactions and can be used to guide the model through complex tasks. Unlike tools or resources, prompts are specifically designed to influence the model's instructions and conversation structure directly from the server side.

Answer

They are automatically injected into the system prompt of every request.

Answer

Prompts are executed as Python code on the server before being sent.

Question 4

Which TWO of the following are benefits of using the Model Context Protocol (MCP) over traditional, custom-built tool-calling implementations?

Accepted Answer

It allows a single server to be used across different host applications like Claude Desktop and IDEs.. MCP provides a standardized interface that decouples the model from the data sources. This standardization reduces the effort needed to integrate new tools and allows for a more modular ecosystem. By using a common protocol, developers can swap out different models or hosts without rewriting their entire integration layer for every tool.

Answer

It automatically encrypts all local data before sending it to the Anthropic API.

Answer

It reduces the need for the model to reason about which tool to use for a task.

Answer

It eliminates the latency associated with network-based API calls.

Question 5

When providing a system prompt alongside a set of tools, what is the best practice for instructing Claude on how to use those tools?

Accepted Answer

Focus the system prompt on the model's persona and high-level goals.. While Claude is trained to use tools based on their JSON definitions, the system prompt can provide critical context on *when* and *why* to use them. Effective system prompts guide the model's strategy, helping it understand complex business logic or multi-step processes that are not apparent from the individual tool descriptions alone.

Answer

Repeat the entire JSON schema of every tool inside the system prompt.

Answer

Tell the model to ignore the tool descriptions and follow the prompt instead.

Answer

Use the system prompt to provide the API keys needed to run the tools.

Question 6

A developer wants to ensure that Claude always uses a specific tool named 'search_documentation' to answer any user query, regardless of the user's intent. Which TWO configurations or strategies are necessary to achieve this? (Select TWO)

Accepted Answer

Set the tool_choice type to 'tool' and provide the name 'search_documentation'.. Forcing tool use is a common pattern for specialized agents. This is achieved by setting the 'tool_choice' parameter to 'tool' and specifying the exact name of the tool. This configuration overrides Claude's default behavior of deciding whether a tool is necessary, ensuring that the defined tool is invoked in every turn of the conversation.

Answer

Set the tool_choice type to 'auto' and include only one tool in the list.

Answer

Set the tool_choice type to 'any' to force the selection of at least one tool.

Answer

Omit the 'description' field in the tool definition to prevent model confusion.

Question 7

The Model Context Protocol (MCP) introduces a standardized way to connect models to data and tools. Which TWO statements accurately describe the roles of MCP Clients and Servers? (Select TWO)

Accepted Answer

An MCP Server can provide tools, resources, and prompt templates to a client.. MCP clarifies the relationship between the model and external resources. Servers are the providers of capabilities, while clients are the consumers that manage the model's interaction with those capabilities. This standardized interface allows a single MCP server to be used across multiple different AI applications without rewriting the tool integration logic.

Answer

The MCP Client is responsible for executing the Python code defined in the server.

Answer

MCP Servers must be hosted on public cloud infrastructure to be accessible.

Answer

The MCP Client defines the JSON schema for all tools provided by the server.

Question 8

A developer is building a Claude-powered support assistant that must query an internal ticketing system through a custom MCP server named 'tickets-mcp'. The server exposes a tool called 'get_ticket' and is launched as a local stdio process. During integration, Claude never emits a 'tool_use' block for 'get_ticket', even when the user explicitly asks about a ticket number. The developer has verified that the tool schema is valid JSON and the server starts without errors. Which configuration issue is the MOST likely cause?

Accepted Answer

The developer forgot to include the MCP server's tool definitions in the 'tools' parameter of the Messages API request, so Claude has no knowledge of 'get_ticket'.. The strongest explanation is that the MCP server's tools were never forwarded into the Messages API 'tools' parameter. MCP standardizes discovery and invocation, but the model only sees tools that the client includes in the request. A healthy server with a valid schema can still produce zero tool_use blocks if its definitions are not passed through, which precisely matches the silent failure in this scenario.

Answer

The stdio server must be started with the '--expose-tools' flag before Claude can invoke any tool it defines.

Answer

The 'tickets-mcp' server was configured with the 'resource' capability instead of the 'tools' capability, so 'get_ticket' is not advertised to Claude.

Answer

The 'get_ticket' tool description exceeds 1024 characters, causing Claude to silently ignore the tool during planning.

Question 9

A developer is implementing a weather-reporting agent using Claude 3.5 Sonnet. After Claude generates a tool_use block for the 'get_weather' tool, the developer fetches the data. What is the correct next step to ensure Claude can finalize its response to the user?

Accepted Answer

Send a new user message containing a 'tool_result' block with the 'tool_use_id'.. The tool use lifecycle requires a multi-turn interaction where the model first requests a tool execution. Once the developer executes the tool locally, they must return the result to Claude in a new 'user' message with a 'tool_result' block. This allows Claude to incorporate the external data into its final synthesis and provide an accurate answer to the original query.

Answer

Append the tool results directly to the end of the previous assistant message.

Answer

Update the system prompt with the new weather data and restart the session.

Answer

Issue a second assistant message that includes the weather data as a JSON string.

Question 10

In the Model Context Protocol (MCP) architecture, which component is responsible for providing specific resources, tools, and prompts to the rest of the ecosystem?

Accepted Answer

The MCP Server. MCP is designed as a client-server architecture to standardize how AI models access external data and functions. The MCP Server is the provider in this relationship, exposing specific capabilities such as local files, database schemas, or API integrations. Understanding this role is fundamental for developers building custom integrations that extend Claude's capabilities beyond its training data.
