mychem.chemicals.annotation
Retrieve comprehensive annotation for a single chemical compound by its InChIKey (e.g. "BSYNRYMUTXBXSQ-UHFFFAOYSA-N"), ChEMBL ID (e.g. "CHEMBL25"), PubChem CID (e.g. "CID2244"), or DrugBank ID (e.g. "DB00945"). Returns complete annotation from 16+ integrated databases: ChEBI chemical definition, ...

What mychem.chemicals.annotation does on Apibase
AI agents call mychem.chemicals.annotation 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 |
|---|---|---|---|
fields | string | — | Comma-separated annotation fields to retrieve. Default: chebi.name, chebi.definition, chebi.formula, chebi.mass, chembl.pref_name, chembl.max_phase, chembl.mole |
chem_id | string | Yes | Chemical identifier to look up. Accepts: InChIKey (primary ID, e.g. "BSYNRYMUTXBXSQ-UHFFFAOYSA-N"), ChEMBL ID (e.g. "CHEMBL25"), PubChem CID (e.g. "CID2244"), o |

Why mychem.chemicals.annotation is rated Low
Tool queries chemical databases and returns read-only annotation data without modification or side effects.
From the tool's definition Retrieve comprehensive annotation for a single chemical compound by identifier
Attacks that exploit this kind of access
The rule that runs mychem.chemicals.annotation 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 mychem.chemicals.annotation, this is the rule to start with:
mychem.chemicals.annotation 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 mychem.chemicals.annotation call is checked against it from then on.
Questions about mychem.chemicals.annotation
Retrieve comprehensive annotation for a single chemical compound by its InChIKey (e.g. "BSYNRYMUTXBXSQ-UHFFFAOYSA-N"), ChEMBL ID (e.g. "CHEMBL25"), PubChem CID (e.g. "CID2244"), or DrugBank ID (e.g. "DB00945"). Returns complete annotation from 16+ integrated databases: ChEBI chemical definition, IUPAC name, and synonyms; ChEMBL clinical development phase (0–4), molecule type, ATC therapeutic classification, Lipinski Ro5 properties (MW, XLogP, HBD, HBA, PSA, rotatable bonds), black-box warning flag, and withdrawal status; PubChem structural identifiers (CID, molecular formula, molecular weight, InChI, SMILES, heavy atom count, complexity score); DrugBank approved indication, mechanism of action, drug targets with gene names and pharmacological actions; PharmGKB clinical pharmacogenomics annotation count; SIDER reported side effects; and NDC product codes. Essential for drug discovery, cheminformatics pipelines, pharmacogenomics analysis, and clinical safety review. It is categorised as a Read tool in the Apibase MCP Server, which means it retrieves data without modifying state.
mychem.chemicals.annotation accepts 2 parameters: fields, chem_id. Required: chem_id. 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 mychem.chemicals.annotation: 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.
mychem.chemicals.annotation 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 mychem.chemicals.annotation 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 mychem.chemicals.annotation. 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.
mychem.chemicals.annotation 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.
