AI agents call search_by_field_value to retrieve information from Scrumdo without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Search and field-value lookups are read-only operations that retrieve data without modification or execution. The lack of description lowers confidence slightly, but the name's clear indication of a search/query function and the context of write/execute sibling tools strongly suggest this is a data retrieval tool with no side effects.
From the tool's definition Tool name 'search_by_field_value' indicates a query/search operation. The description is empty, but sibling tools like 'add_comment', 'assign_card', and 'archive_card' are clearly write/execute operations, making this search tool distinctly a read operation…
Attacks that exploit this kind of access
search_by_field_value. It is categorised as a Read tool in the Scrumdo MCP Server, which means it retrieves data without modifying state.
Register the Scrumdo MCP server in PolicyLayer and add a rule for search_by_field_value: 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 Scrumdo. Nothing to install.
search_by_field_value 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_by_field_value 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_by_field_value. 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_by_field_value is provided by the Scrumdo MCP server (scrumdollc/scrumdo-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
