search_fields
AI agents call search_fields to retrieve information from MCP Atlassian without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool name and naming convention align with Read operations (search, get, list). The empty description prevents higher confidence, but the sibling tool context—all Read/Write/Execute operations with no Destructive tools exposed—indicates this is a metadata lookup/query function. Blast radius is minimal as field searches have no side effects.
From the tool's definition Tool name 'search_fields' indicates field discovery/querying capability. Description is empty, limiting direct evidence.
Attacks that exploit this kind of access
search_fields. It is categorised as a Read tool in the MCP Atlassian MCP Server, which means it retrieves data without modifying state.
Register the MCP Atlassian MCP server in PolicyLayer and add a rule for 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 MCP Atlassian. Nothing to install.
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 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 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.
search_fields is provided by the MCP Atlassian MCP server (omkar9854/mcp-atlassian-onpremdc). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
