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 | $0.00601 | $0.00601 |
| Opus 5 | $0.00300 | $0.00300 |
| Sonnet 5 | $0.00120 | $0.00120 |
| Haiku 4.5 | $0.00060 | $0.00060 |
Grade A, and why
farmbot-agent-cli-mcp CLAUDE.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 9d 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.
How it starts
The opening of the file, as written. The whole thing — 60 lines — stays where its author put it; the contents beside it link to each section on GitHub.
farmbot-agent
TypeScript CLI + MCP server for FarmBot hardware control.
Architecture
- Two entry points:
src/cli.ts(Commander) andsrc/mcp.ts(McpServer via stdio) - No controller layer — CLI commands and MCP tools call services directly
- ConnectionManager handles MQTT lifecycle:
EphemeralConnection(CLI): connect, run one command, force-close, exitPersistentConnection(MCP): lazy-connect, reuse across tool calls, reconnect on disconnect
- Shared Zod schemas in
src/types/schemas.ts— single source of truth for CLI args and MCP tool input
Key Constraints
- ESM only (
"type": "module") - Strict TypeScript:
strict,noUncheckedIndexedAccess,exactOptionalPropertyTypes - Every function returns
Result<T>, never throws - Every MQTT command wrapped in
withTimeout()— farmbot-js has no built-in timeouts - farmbot-js has no
disconnect()— usebot.client!.end(true)to force-close
Commands
| CLI | MCP Tool | Description |
|---|---|---|
farmbot login |
N/A (env var) | Authenticate and store token |
farmbot status |
farmbot_status |
Device position, state, firmware |
farmbot move |
farmbot_move |
Move to position (absolute/relative) |
farmbot home |
farmbot_home |
Go to home position |
farmbot e-stop |
farmbot_emergency_stop |
Emergency stop |
farmbot unlock |
farmbot_unlock |
Unlock after e-stop |
farmbot lua |
farmbot_lua |
Execute Lua on device |
farmbot_get_position |
Get current position only | |
farmbot_get_device_info |
Get device config info |
Testing
npm test # vitest
npm run typecheck # tsc --noEmit
npm run build # tsup
Mock at the ConnectionManager boundary, not at MQTT level.
Adding a New Command
- Add Zod schema to
src/types/schemas.ts - Add CLI command to
src/cli.ts - Add MCP tool to
src/mcp.ts— MUST have parity with CLI - Add tool annotations (
readOnlyHint,destructiveHint) - Wrap MQTT calls in
withTimeout() - Add test
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.

farmbot-agent-cli-mcp CLAUDE.md is an instructions file published in the GitHub repository kieranklaassen/farmbot-agent-cli-mcp (3 stars, last pushed 4mo ago), licensed MIT. It adds 601 tokens to every session, about $0.0030 per session on Opus 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.
