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 | $0.00673 | $0.00673 |
| Opus 5.5 | $0.00269 | $0.00269 |
| Sonnet 5.5 | $0.00135 | $0.00135 |
| Haiku 4.5 | $0.00067 | $0.00067 |
Grade A, and why
opencode-cli-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 1mo 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-cli-mcp - Agent Guide
Overview
MCP server wrapping the opencode CLI (opencode serve) for AI agent
orchestration: launch/poll/review agent runs, session CRUD + diff, offline session depot over
the opencode SQLite DB, .mcpb installs, and graceful shutdown. Ships a unified FastAPI backend
(REST /api/* + FastMCP /mcp on one port) and a Vite/React fleet-standard dashboard.
Quick-Ref Commands
| Command | What it does |
|---|---|
just serve |
Run MCP server (stdio) |
just api |
Run unified backend (api.main, :10951) |
just web |
Run Vite frontend (:10950) |
just certify |
All gates: ruff, pytest, pyright, tsc, biome |
just test / just check |
pytest / ruff check + format |
.\start.ps1 |
Full stack: opencode serve + backend + frontend |
Ports
| Port | Service |
|---|---|
| 10950 | Frontend (Vite) |
| 10951 | Unified backend (REST /api/* + MCP /mcp) |
| 4097 | backend-owned opencode serve (NOT 4096 — the desktop app's password-locked serve lives there) |
Standards
- FastMCP 3.2+ portmanteau tool pattern - tools use
operationenum param; responses are structured dicts withsuccess,message, domain-specific fields. - 6 primary tools (
opencode_runs,opencode_sessions,opencode_depot,opencode_system,opencode_mcpb_install,opencode_shutdown) + 15 legacy atomic aliases (0.3.0 removes them). - Dual transport: stdio (Claude Desktop) + unified HTTP backend (
api.main). - See mcp-central-docs for fleet-wide standards.

What this file has done since we first saw it
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.

opencode-cli-mcp AGENTS.md is an instructions file published in the GitHub repository sandraschi/opencode-cli-mcp (3 stars, last pushed yesterday), licensed MIT. It adds 673 tokens to every session, about $0.0027 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
