Frequently asked questions

Elthio MCP is categorized under Biology & Bioinformatics and uses an install path we have not confirmed yet. ChemCP belongs to Biology & Bioinformatics and uses a local stdio subprocess. Pick Elthio MCP 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. Elthio MCP has no confirmed install command yet — follow its own setup instructions.

Elthio MCP 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 elthio-mcp and chemcp as separate keys in the same mcpServers object, and your assistant will call tools from either one.

On AllMCPs, Elthio MCP has a quality signal of 32/100 (Emerging) with 2 views, 0 installs and 1 GitHub stars. ChemCP has 40/100 (Fair) with 2 views, 0 installs and 2 GitHub stars.
