seam-self-host

seam-self-host is the compiled Linux/x86-64 self-hosted SEAM agent-memory node. It installs the opaque /v1 service plus the local MCP stdio surface used by Claude, Cursor, Gemini, and other MCP-capable agents.

The wheel contains native extension modules and does not ship the seam_runtime Python source. Native compilation raises the cost of casual inspection; it is not a cryptographic boundary against an administrator who controls the host. See the self-host security documentation for the complete protection model.

This first wheel supports CPython 3.12 on manylinux_2_28_x86_64.

Run

The HTTP node requires an API token of at least 32 characters and a writable database path:

export SEAM_API_TOKEN_FILE=/run/secrets/seam-api-token
export SEAM_SERVER_DB=/var/lib/seam/seam.db
seam-self-host

The server listens on 0.0.0.0:8765 by default. Keep it on a trusted network or place an authenticated TLS reverse proxy in front of it.

An entitlement is optional and gates no capability. When no entitlement is mounted, the node logs that it is running unentitled under BUSL-1.1. Supported deployments may set SEAM_SELFHOST_ENTITLEMENT_PATH and SEAM_SELFHOST_PUBLIC_KEY_PATH; a mounted entitlement is verified and a forged or malformed one fails closed.

MCP

Connect an MCP client to the wheel's stdio command:

seam-mcp --db /var/lib/seam/seam.db

The MCP server exposes the same three operations as the HTTP surface — seam_remember, seam_recall, and seam_context — talking directly to the local database instead of over the network. Run it only for a trusted local client and protect the database with operating-system permissions.
