mychem.chemicals.search
Search the MyChem.info database of 197M+ annotated chemical compounds using a flexible query syntax. Query by: common name (e.g. "aspirin"), IUPAC name (e.g. "acetylsalicylic acid"), InChIKey (e.g. "BSYNRYMUTXBXSQ-UHFFFAOYSA-N"), molecular formula (e.g. "C9H8O4"), ChEMBL ID (e.g. "CHEMBL25"), Pub...

What mychem.chemicals.search does on Apibase
AI agents call mychem.chemicals.search 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 |
|---|---|---|---|
q | string | Yes | Chemical search query. Supports: common name (e.g. "aspirin"), IUPAC name (e.g. "acetylsalicylic acid"), InChIKey (e.g. "BSYNRYMUTXBXSQ-UHFFFAOYSA-N"), molecula |
size | integer | — | Maximum number of chemical results to return (1–50, default 10). |
fields | string | — | Comma-separated annotation fields to return per hit. Default: chebi.name, chebi.definition, chebi.formula, chebi.mass, chembl.pref_name, chembl.max_phase, chemb |
scopes | string | — | Comma-separated fields to search within. Default: searches all text fields. Examples: "chebi.name,chembl.pref_name,drugbank.name" to search only common names, o |

Attacks that exploit this kind of access
The rule that runs mychem.chemicals.search 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.search, this is the rule to start with:
mychem.chemicals.search 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.search call is checked against it from then on.
Questions about mychem.chemicals.search
Search the MyChem.info database of 197M+ annotated chemical compounds using a flexible query syntax. Query by: common name (e.g. "aspirin"), IUPAC name (e.g. "acetylsalicylic acid"), InChIKey (e.g. "BSYNRYMUTXBXSQ-UHFFFAOYSA-N"), molecular formula (e.g. "C9H8O4"), ChEMBL ID (e.g. "CHEMBL25"), PubChem CID (e.g. "pubchem.cid:2244"), DrugBank ID (e.g. "DB00945"), or field-scoped queries (e.g. "drugbank.groups:approved AND chembl.max_phase:4"). Each result includes chemical names across databases (ChEBI, ChEMBL, DrugBank, PharmGKB), structural properties (molecular formula, weight, XLogP, H-bond donors/acceptors, TPSA, rotatable bonds), drug development phase, ATC classification codes, and approval status. Integrates DrugBank, ChEMBL, ChEBI, PubChem, PharmGKB, SIDER, DrugCentral, NDC, and 16+ annotation sources. It is categorised as a Read tool in the Apibase MCP Server, which means it retrieves data without modifying state.
mychem.chemicals.search accepts 4 parameters: q, size, fields, scopes. Required: q. 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.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 Apibase. Nothing to install.
mychem.chemicals.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 mychem.chemicals.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 mychem.chemicals.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.
mychem.chemicals.search 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.
