What is opencode_mcp AGENTS.md?

Repository instructions for using opencode-mcp-bridge, an MCP server that lets coding agents delegate work to the OpenCode command-line tool. The instructions explain setup, task handling, and known problems such as provider authentication.

Delegating coding, refactoring, testing, and code-generation tasks to OpenCode, while checking the bridge guide, logs, events, and saved checkpoints.

They give an agent a current guide before it delegates coding work, reducing mistakes in model selection, asynchronous jobs, batching, and failure diagnosis.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.01650	$0.01650
Opus 5.5	$0.00660	$0.00660
Sonnet 5.5	$0.00330	$0.00330
Haiku 4.5	$0.00165	$0.00165

Security

Grade A, and why

opencode_mcp AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

opencode-mcp-bridge — Agent Integration Guide

This file follows the AGENTS.md convention: a single, tool-agnostic set of instructions any coding agent (Claude Code, Antigravity, Cursor, Windsurf, Codex CLI, JetBrains AI, etc.) can read to work with this repository correctly.

Start here

Call the opencode_guide MCP tool first, before delegating anything. It returns the complete, always-current behavioral guide (model selection, async workflow, batch orchestration, failure diagnosis) generated live from the running bridge's actual state — treat it as authoritative over the summary below if they ever disagree.

What this is

An MCP server (opencode-mcp-bridge) that lets any agent delegate coding, refactoring, testing, and generation tasks to the OpenCode CLI as a subagent — via OpenCode's own opencode serve HTTP/SSE API. One persistent server process, one shared event stream, no PTY, no per-task re-authentication.

Binary target: opencode
Events log: ~/.opencode-mcp-events.jsonl
Bridge logs: ~/.opencode-bridge/logs/bridge.log
Checkpoints: ~/.opencode-bridge/checkpoints/
Server singleton state: ~/.opencode-bridge/server.json

Known gotcha: provider auth

google/* models (Antigravity/Gemini) route through a third-party auth plugin that can intermittently fail with ModelUnavailableError if its cached OAuth token has expired. If a session goes straight to error, check opencode_health's last_error before assuming it's a bridge bug — that error means the provider needs re-auth (opencode auth login <provider>, run manually in a terminal), not a code fix. opencode/* free-tier models have no such dependency and always work. For image generation specifically, consider a dedicated image-gen tool/provider if one is available in your environment — OpenCode's google/* image models ride the same auth path and are equally exposed to the failure above.

If opencode_server_health reports the server unhealthy or wedged, opencode_server_restart forces a clean respawn — but this is rarely needed manually, since the bridge already restarts automatically the moment it detects a failed session.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
