You can access the Chemical Compound Lookup: PubChem Formula, Weight & SMILES programmatically from your own applications by using the Apify API. You can also choose the language preference from below. To use the Apify API, you’ll need an Apify account and your API token, found in API & Integrations in Apify Console.
{ "mcpServers": { "apify": { "type": "http", "url": "https://mcp.apify.com/?tools=fetch-actor-details,smilemask/pubchem-compound-lookup" } }}The configuration above connects to the hosted Apify MCP server with the Chemical Compound Lookup: PubChem Formula, Weight & SMILES Actor already loaded. It uses OAuth, so your client opens a browser window to sign you in to Apify on first use. No API token is needed. Clients without OAuth support can authenticate with an Authorization: Bearer header carrying an API token from API & Integrations in Apify Console.
Get a ready-to-use configuration for your MCP client with the Chemical Compound Lookup: PubChem Formula, Weight & SMILES Actor preconfigured at https://mcp.apify.com/?tools=fetch-actor-details,smilemask/pubchem-compound-lookup.
You can connect to the Apify MCP Server using clients like Tester MCP Client, or any other MCP client of your choice.
