What it does

Patsnap Chemistry Small Molecule is an agent skill from patsnap/mcp. Patsnap Chemistry & Small Molecule MCP for AI agents. Intelligent chemical small molecule analysis platform, covering chemical structure search, structure details analysis, and ADMET property prediction.

Its SKILL.md is about 640 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `README.md` and `package.json`).

It sits in Research & Science, covering Drug discovery and cheminformatics. It works with Model Context Protocol. The repository describes itself as: MCP server for 200M+ patents, scientific literature, chemistry and pharma records. Search prior art and R&D intelligence powered by PatSnap's proprietary databases via Claude… The licence is Apache-2.0.

When your agent uses it

  • Tasks that involve Drug discovery and cheminformatics

Example prompts

  • “/patsnap-chemistry-small-molecule”

Requirements

  • A credential in YOUR_API_KEY

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. Chemical Entity Recognition
  2. Structure Search
  3. Property Prediction
  4. Output Synthesis

What it can do on your machine

Read from SKILL.md and the folder at commit 7a4b429. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are json).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • connect.patsnap.com

    Also links to:

    • open.patsnap.com
    • eureka.patsnap.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Patsnap Chemistry Small Molecule loads about 643 tokens when it runs. Until then it costs about 59 tokens; SKILL.md has 193 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~59
When it runs · the whole SKILL.md, loaded when a task matches
~643

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Patsnap Chemistry & Small Molecule

This skill connects your AI agent to Patsnap's Chemistry & Small Molecule MCP server — providing professional-grade life sciences intelligence.

Intelligent chemical small molecule analysis platform, covering chemical structure search, structure details analysis, and ADMET property prediction.

Prerequisites

This skill requires the Patsnap Chemistry & Small Molecule MCP server to be configured in your environment:

json
{
  "mcpServers": {
    "chemistry_small_molecule": {
      "url": "https://connect.patsnap.com/f71d33/logic-mcp?apikey=YOUR_API_KEY",
      "type": "streamableHttp"
    }
  }
}

Get your API key at open.patsnap.com. For the full list of available tools and input parameters, refer to the official MCP server documentation: https://open.patsnap.com/marketplace/mcp-servers/chemistry-small-molecule


Instructions for AI Agents

Step 1: Chemical Entity Recognition

When a user mentions a chemical name, drug, or SMILES string, resolve it to a standard structure or identifier.

Use structure_search for exact matches or similarity analogs. Fetch full details with structure_fetch.

Step 3: Property Prediction

Use admet_predict to evaluate drug-likeness and pharmacokinetic properties.

Step 4: Output Synthesis

Present SMILES/InChI, scaffold descriptions, and tabular comparisons of analogs.


Example Workflows

Lead Optimization
  1. Run structure_search with a lead SMILES.
  2. Fetch analog details with structure_fetch.
  3. Predict ADMET with admet_predict to prioritize candidates.
