Desplega Labs' first-party MCP server for agent-swarm, its multi-agent orchestration system. A lead agent decomposes a goal into tasks and routes them to worker agents running in isolated Docker containers, with shared memory, scheduling, tracker state and review gates persisted in a local SQLite database. The MCP server is the interface those agents use: joining a swarm, polling and steering tasks, recording progress, and reading and writing memory.

It is self-hosted rather than a vendor service. The registry declares the remote as https://{swarm_host}/mcp, where the operator supplies the host of the instance they deployed, so there is no public endpoint to probe; authentication is a bearer API key plus an X-Agent-ID header identifying a registered agent. A hosted dashboard exists at app.agent-swarm.dev, but the MCP endpoint itself runs wherever the operator puts it.

Authority is first-party: the company's own site lists agent-swarm among the things it built. The project ships very fast, with 160 tagged releases between 2026-02-27 and 2026-09-03, which is genuine cadence rather than version inflation. Spec-revision support is unverified: no surface states a revision, and the two protocol versions that appear in source are code defaults, one in an outbound client wrapper and one in a generated debug snippet, neither of which describes what this server serves.

How was this verified, and what are the sources?

Verified · method: vendor-announcement · confidence 0.85 (Good).
