What chembl-list-activities does on Meta Data Mcp
AI agents call chembl-list-activities to retrieve information from Meta Data Mcp without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why chembl-list-activities is rated Low
This is a read-only query tool that retrieves activity data from ChEMBL (a public chemistry database). It uses the 'list' verb and accepts optional filtering parameters, which is characteristic of safe, non-destructive data retrieval. The low severity reflects that misuse would only expose publicly available scientific data with no harmful side effects.
From the tool's definition Tool name 'chembl-list-activities' with description 'List ChEMBL activities with optional molecule filter' indicates data retrieval from an open chemistry database. The verb 'list' and the optional filter pattern are consistent with query-only operations.
Attacks that exploit this kind of access
The rule that runs chembl-list-activities safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Meta Data Mcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For chembl-list-activities, this is the rule to start with:
chembl-list-activities is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Meta Data Mcp, apply this rule, and every chembl-list-activities call is checked against it from then on.
Questions about chembl-list-activities
List ChEMBL activities with optional molecule filter. It is categorised as a Read tool in the Meta Data Mcp MCP Server, which means it retrieves data without modifying state.
Register the Meta Data MCP server in PolicyLayer and add a rule for chembl-list-activities: 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 Meta Data Mcp. Nothing to install.
chembl-list-activities 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 chembl-list-activities 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 chembl-list-activities. 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.
chembl-list-activities is provided by the Meta Data MCP server (pypi:meta-data-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
