Frequently asked questions

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

ChemCP has no declared pricing — check the project's own site. Mychart 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 chemcp and mychart as separate keys in the same mcpServers object, and your assistant will call tools from either one.

On AllMCPs, ChemCP has a quality signal of 40/100 (Fair) with 1 views, 0 installs and 2 GitHub stars. Mychart has 53/100 (Good) with 2 views, 0 installs and 0 GitHub stars.
