Frequently asked questions
Codeindex is categorized under Biology & Bioinformatics and uses a local stdio subprocess. Next Devtools MCP belongs to Developer Tools and uses a local stdio subprocess. Pick Codeindex for biology & bioinformatics work and Next Devtools MCP for developer tools.
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.
Codeindex has no declared pricing — check the project's own site. Next Devtools MCP is listed as free. Auth: no auth required. 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 codeindex and vercel-next-devtools-mcp as separate keys in the same mcpServers object, and your assistant will call tools from either one.
