Frequently asked questions
Pubchem MCP Server is categorized under Biology & Bioinformatics and uses an install path we have not confirmed yet. Mirobody belongs to Biology & Bioinformatics and uses an install path we have not confirmed yet. Pick Pubchem MCP Server for biology & bioinformatics work and Mirobody for biology & bioinformatics.
Neither server has a confirmed install command yet, so we don't publish a guessed config. Follow each project's own setup instructions, linked from its listing page.
Pubchem MCP Server is listed as free. Auth: no auth required. Mirobody is bring-your-own-key: usage is billed by the API provider you supply a key for. 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 pubchem-mcp-server and mirobody as separate keys in the same mcpServers object, and your assistant will call tools from either one.
