How do I install Seam Runtime?

Copy the stdio config for Cursor, Claude Desktop, Claude Code, or VS Code on this page. It uses the publisher's install, not a PlugMCP proxy.

Does Seam Runtime need an API key?

The publisher lists these environment variables: SEAM_DB_PATH, SEAM_PGVECTOR_DSN.

What transport does Seam Runtime use?

Seam Runtime runs locally over stdio.

Power your agent

Add this server

The publisher's own command. Not a PlugMCP endpoint.

Local command

uvx seam-runtime==1.3.1

Credentials from the publisher

SEAM_DB_PATH — Path to the local SQLite memory database. Defaults to a per-user data directory if unset.
SEAM_PGVECTOR_DSN — Optional Postgres/pgvector DSN for the vector adapter. If unset, SEAM runs on the built-in SQLite vector store.

Remote URL or a command on your machine? How the two installs differ

Run on PlugMCP

Host a copy with our keys and logs.

A new server you create. It is not this listing's official endpoint. Use the publisher install when you want their URL and their credentials.
