Frequently asked questions
Pg Aiguide is categorized under Databases and uses an install path we have not confirmed yet. MCP Server Qdrant belongs to Databases and uses a local stdio subprocess. Pick Pg Aiguide for databases work and MCP Server Qdrant for databases.
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. Pg Aiguide has no confirmed install command yet — follow its own setup instructions.
Pg Aiguide has no declared pricing — check the project's own site. MCP Server Qdrant is listed as free. Auth: api key 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 pg-aiguide and qdrant-mcp-server-qdrant as separate keys in the same mcpServers object, and your assistant will call tools from either one.
