An agent using MCP tools to manage GitHub repository settings is repeatedly calling the 'update_branch_protection' tool with missing required parameters, causing tool errors on every run. Logs confirm the agent always has the correct branch name available in context. Which tool configuration refinement will most directly fix this recurring tool misuse?
Select an answer to reveal the explanation.
Short Explanation
When the agent keeps missing required parameters, the fix is to make the tool contract impossible to misunderstand. Improve the JSON schema description with clear parameter names, types, and examples so it builds valid calls. You don't need to remove, retry, or replace the tool.
Full Explanation
Repeated tool misuse with missing required parameters typically signals a tool description problem rather than a model reasoning problem. The agent has the information it needs, because the branch name is available in context, but it consistently fails to construct a complete, valid tool call. That pattern points to an underspecified tool schema.
Improving the tool's JSON schema description is the correct refinement because the JSON schema description is the primary interface through which an agent understands how to call a tool. If required parameters are not clearly named, their types are ambiguous, or no examples are provided, the agent is likely to omit them or pass incorrect values. Enumerating required fields, specifying types such as string, boolean, or array of strings, and adding example values directly addresses the agent's incorrect call construction.
Removing the tool from the agent's tool list eliminates the capability the agent needs to complete its task. That is not a fix; it is abandoning the feature. Removing a tool should only happen when the tool is genuinely inappropriate for the agent's role.
Adding a retry loop in the agent's workflow will cause the agent to repeat the same broken call up to three times. If the call is missing required parameters, retrying it without changing anything will produce the same error each time. Retries help with transient failures, not consistent structural errors.
Switching the agent to a different MCP server that offers a simpler version of the branch protection tool is a heavy-handed workaround that introduces migration risk and may introduce new tool mismatches. The correct fix is to improve the tool description on the existing server, which is a lightweight, targeted change.
