AI agents call jira_search_fields to retrieve information from Jiraxmcp without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves field metadata from Jira without modifying, creating, deleting, or executing operations. It is a standard read-only query operation with minimal blast radius if misused—an AI agent could retrieve field information but cannot damage systems, delete data, or trigger external operations.
From the tool's definition Tool name and description indicate search functionality: 'Search Jira fields by name, description, or id.' The verb 'search' combined with 'fields' (metadata) indicates retrieval/query without modification.

Register the Jirax MCP server in PolicyLayer and add a rule for jira_search_fields: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Jiraxmcp. Nothing to install.
jira_search_fields is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the jira_search_fields rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for jira_search_fields. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
jira_search_fields is provided by the Jirax MCP server (vaibhavpandeyvpz/jiraxmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
