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 | $0.01750 | $0.01750 |
| Opus 5.5 | $0.00700 | $0.00700 |
| Sonnet 5.5 | $0.00350 | $0.00350 |
| Haiku 4.5 | $0.00175 | $0.00175 |
Grade A, and why
nt-mcp-server 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 today.
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 — 66 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
MCP server exposing FRC NetworkTables (NT4) to AI agents. Reads/writes/monitors a robot's network tables; primary target is a local RobotPy sim (python -m robotpy sim on 127.0.0.1:5810).
Run
uv run nt-mcp-server # stdio MCP server (equiv: python -m nt_mcp_server)
uv run nt-recorder --prefixes /SmartDashboard/ --output-dir recordings # standalone CLI, not an MCP tool
Server runs on stdio — MCP clients (opencode) launch it via opencode.jsonc (uv run nt-mcp-server). It connects to 127.0.0.1:5810 by default. Live NT is optional; offline tools work without any connection.
Architecture
Package nt_mcp_server/ (4 modules, strict layering — each lower layer knows nothing about the one above):
__init__.py— FastMCPmcpinstance + all 16 tool definitions. Imports no ntcore. Tools delegate to the module-levelmanager = NTManager(). Sync tools (nt_write_topics,nt_disconnect, etc.) are plain functions; read tools areasync.nt_manager.py—NTManager: pure NT4 client lifecycle + reads/writes/subscribe streams. No MCP/FastMCP imports. Lazy default instance viantcore.NetworkTableInstance.getDefault().nt_recorder.py— two unrelated pieces: thent-recorderCLI (argparsemain), and the synchronous offline NDJSON reader API (list_recordings,get_history,subscribe_offline, …;get_history/subscribe_offlinetakereturn_meta=Trueto addrows/total_rows/truncated) used by the offline MCP tools.nt_types.py— value normalization (to_jsonable), homogeneous-list classification, summaries. Pure, no connection state.
16 tools = 13 live + 3 offline (nt_list_recordings, nt_get_recording_info, nt_query_recording). The live tools include a nonblocking nt_start_recording / nt_stop_recording pair for human-controlled test windows. Every live tool response carries a top-level connected flag; disconnected reads return {"connected": false, "error": ...} instead.
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.

nt-mcp-server AGENTS.md is an instructions file published in the GitHub repository Mzzj114/nt-mcp-server (1 stars, last pushed yesterday), licensed MIT. It adds 1,750 tokens to every session, about $0.0070 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.
