What chemistry.pubchem.properties does on Apibase
AI agents call chemistry.pubchem.properties to retrieve information from Apibase without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
cid | integer | Yes | PubChem Compound ID (CID) — get from compound_search results |
Parameters from the server's own tool schema.
Why chemistry.pubchem.properties is rated Low
Queries public chemical property data without modification, deletion, or external side effects.
From the tool's definition Get full physical and chemical properties for a compound by PubChem CID
Attacks that exploit this kind of access
The rule that runs chemistry.pubchem.properties safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Apibase, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For chemistry.pubchem.properties, this is the rule to start with:
chemistry.pubchem.properties 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 Apibase, apply this rule, and every chemistry.pubchem.properties call is checked against it from then on.
Questions about chemistry.pubchem.properties
Get full physical and chemical properties for a compound by PubChem CID — molecular formula, weight, SMILES, InChI, InChIKey, XLogP, H-bond donors/acceptors, exact mass, topological polar surface area, complexity, charge, heavy atom count (PubChem / NCBI). It is categorised as a Read tool in the Apibase MCP Server, which means it retrieves data without modifying state.
chemistry.pubchem.properties accepts 1 parameter: cid. Required: cid. The full parameter table on this page comes from the server's own tool schema.
Register the Apibase MCP server in PolicyLayer and add a rule for chemistry.pubchem.properties: 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 Apibase. Nothing to install.
chemistry.pubchem.properties 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 chemistry.pubchem.properties 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 chemistry.pubchem.properties. 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.
chemistry.pubchem.properties is provided by the Apibase MCP server (apibase-mcp-client). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
