Frequently asked questions

Puumed is categorized under Biology & Bioinformatics and uses a local stdio subprocess. ChemCP belongs to Biology & Bioinformatics and uses a local stdio subprocess. Pick Puumed for biology & bioinformatics work and ChemCP for biology & bioinformatics.

Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client.

Puumed has no declared pricing — check the project's own site. ChemCP has no declared pricing — check the project's own site. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.

Yes. MCP clients support multiple servers: add puumed and chemcp as separate keys in the same mcpServers object, and your assistant will call tools from either one.
