What is the PubChem MCP Server?
Connect your AI agent to PubChem — the world's largest open chemistry database, maintained by the National Center for Biotechnology Information (NCBI/NIH).
What you can do
- Compound Search — Find chemical compounds by common name (aspirin, caffeine, glucose), IUPAC name, or CAS number across 116M+ indexed compounds
- CID Lookup — Get comprehensive molecular data for any compound by its PubChem Compound ID including formula, weight, SMILES, InChI, and physicochemical properties
- Formula Search — Find all compounds matching a specific molecular formula (e.g., C9H8O4 for aspirin)
How it works
- Subscribe to this server
- Start searching compounds immediately — no API key required
Who is this for?
- Medicinal Chemists — quickly retrieve molecular properties and drug-like characteristics for lead compounds
- Pharmacy Students — look up drug structures, formulas, and physicochemical data during coursework
- Biochemistry Researchers — identify compounds by formula and explore metabolite databases
Built-in capabilities (3)
Get full chemical data for a PubChem compound by CID
Returns molecular formula, weight, SMILES, InChI, XLogP, hydrogen bond donors/acceptors, and complexity. Try: aspirin, caffeine, glucose, penicillin, dopamine. Search PubChem for chemical compounds by name
g. C9H8O4, C8H10N4O2, H2O) and find matching compounds. Find compounds by molecular formula
Why AutoGen?
AutoGen enables multi-agent conversations where agents negotiate, delegate, and collaboratively use PubChem tools. Connect 3 tools through Vinkius and assign role-based access. a data analyst queries while a reviewer validates, with optional human-in-the-loop approval for sensitive operations.
- —
Multi-agent conversations: multiple AutoGen agents discuss, delegate, and collaboratively use PubChem tools to solve complex tasks
- —
Role-based architecture lets you assign PubChem tool access to specific agents. a data analyst queries while a reviewer validates
- —
Human-in-the-loop support: agents can pause for human approval before executing sensitive PubChem tool calls
- —
Code execution sandbox: AutoGen agents can write and run code that processes PubChem tool responses in an isolated environment

Frequently asked questions
Do I need an API key to use PubChem?
No. PubChem PUG REST is completely free and open without any authentication. The only limitation is a rate limit of 5 requests per second and 400 requests per minute, which is more than sufficient for conversational AI usage.
What molecular properties are returned for each compound?
Each compound includes: CID, IUPAC name, molecular formula, molecular weight, canonical SMILES, InChI identifier, XLogP (lipophilicity), hydrogen bond donor count, hydrogen bond acceptor count, and molecular complexity score. These cover Lipinski's Rule of Five for drug-likeness assessment.
Can I search by molecular formula instead of name?
Yes! Use the formula search tool with standard notation (e.g., C8H10N4O2 for caffeine, C9H8O4 for aspirin, H2O for water). PubChem will return all compounds matching that exact formula with their names and properties.
How does AutoGen connect to MCP servers?
Create an MCP tool adapter and assign it to one or more agents in the group chat. AutoGen agents can then call PubChem tools during their conversation turns.
Can different agents have different MCP tool access?
Yes. AutoGen's role-based architecture lets you assign specific MCP tools to specific agents, so a querying agent has different capabilities than a reviewing agent.
Does AutoGen support human approval for tool calls?
Yes. Configure human-in-the-loop mode so agents pause and request approval before executing sensitive MCP tool calls.
