for OpenCode

An open agent with the project graph attached.

OpenCode is operator-controlled by design. Hydrant pairs cleanly: the same project graph, on a hosted endpoint you authenticate to with a PAT — no daemons, no plugins, no vendor lock on where the agent runs.

Point OpenCode at one URL.

Hydrant runs as a hosted MCP server. Authenticate with a personal access token and the same endpoint works across every client.

  1. 1Install OpenCode from opencode.ai
  2. 2Add the mcp.hydrant block to opencode.json, replacing the bearer with your Hydrant PAT
  3. 3Restart OpenCode and confirm the hydrant server appears in the MCP list

Capabilities

The working set agents need.

Same hosted endpoint, same object model. OpenCode can read, write, and walk the project graph from a single MCP connection.
