search
AI agents call search to retrieve information from Mcp Rcsb Pdb without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves data from a scientific database without modifying, deleting, or executing operations. While the tool description is empty, the server context and naming pattern clearly indicate a read-only search operation. The blast radius is minimal—search queries cannot cause harm beyond potential information disclosure, which is not sensitive for public PDB data.
From the tool's definition Tool name is 'search' on a server that 'enables querying and retrieving experimental protein structures from the RCSB Protein Data Bank, including text search.' The server description explicitly lists 'text search' as a query capability.
Attacks that exploit this kind of access
search. It is categorised as a Read tool in the Mcp Rcsb Pdb MCP Server, which means it retrieves data without modifying state.
Register the Mcp Rcsb Pdb MCP server in PolicyLayer and add a rule for search: 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 Rcsb Pdb. Nothing to install.
search 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 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. 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 is provided by the Mcp Rcsb Pdb MCP server (pipeworx-io/mcp-rcsb-pdb). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
