Seamless MCP server

Seamless

An AI coding agent rediscovers the same constraint every session, because nothing it learns survives the context window. Run two agents against the same backlog and they pick the same step and build it twice. And the products that promise to fix this keep your project's memory in someone else's database.

Seamless is a local-first memory and coordination substrate for AI coding agents. Works with Claude Code, Codex CLI, and any MCP client. It also works from chats in the Claude desktop app, for long-running work that isn't code: see Seamless in the Claude app.

It gives a fleet of agents a shared, durable memory and a way to divide work without colliding: memories with a supersession lifecycle, hybrid recall, a dependency-aware task queue with lease-based claiming, captured plans, and research trials. Durable knowledge is stored as markdown files on disk; the seamlessd daemon indexes it, serves it over MCP, and renders a web console, while the companion seam CLI gives headless agents a direct interface.

Design principles

dependency-aware ready-queue, atomic lease-based task claiming, and plans composed of notes and steps, so agents divide labor instead of colliding.

• Built for a fleet, not a lone agent. Real coordination primitives: a

with YAML frontmatter under ~/.seamless -- git-diffable, greppable, hand-editable. SQLite indexes those files and also stores operational state such as sessions, tasks, trials, and events, so back up the whole data directory.

• Files are the source of truth. Every memory and note is a markdown file

deduplicating and archiving to flagging dead weight and knowledge gaps -- only proposes; applying is an explicit action. Supersession preserves provenance, so nothing is silently rewritten.

• Curation proposes, humans dispose. Every gardener pass -- from

pure-Go SQLite, no Node, no separate vector engine, no cloud account.

• Small, self-contained runtime. A static Go daemon and CLI, no CGO,

How it compares

The agent-memory space splits into a few recognizable categories. By category, because categories do not go stale:
