Full UniProtKB protein entry by accession (e.g. P04637): names, gene, organism, sequence length + molecular weight, function, subcellular locations, GO terms, PDB structures, keywords. Protein-centric sibling to bio.gene.
AI agents call bio.protein to retrieve information from Mcp without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a pure data retrieval operation querying a public biological database (UniProtKB). It returns structured protein information without creating, modifying, deleting, or executing any operations. No financial transactions, code execution, or destructive actions are involved. The 'pay-per-call' aspect of the 2s.io platform indicates billing for API usage, but the tool itself only reads data.
From the tool's definition Tool retrieves protein data from UniProtKB by accession number, returning informational fields: names, gene, organism, sequence length, molecular weight, function, subcellular locations, GO terms, PDB structures, and keywords.
Attacks that exploit this kind of access
Full UniProtKB protein entry by accession (e.g. P04637): names, gene, organism, sequence length + molecular weight, function, subcellular locations, GO terms, PDB structures, keywords. Protein-centric sibling to bio.gene. It is categorised as a Read tool in the Mcp MCP Server, which means it retrieves data without modifying state.
Register the MCP server in PolicyLayer and add a rule for bio.protein: 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. Nothing to install.
bio.protein 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 bio.protein 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 bio.protein. 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.
bio.protein is provided by the MCP server (@2sio/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
