Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00175 | $0.01560 |
| Opus 5 | $0.00088 | $0.00780 |
| Sonnet 5 | $0.00035 | $0.00312 |
| Haiku 4.5 | $0.00017 | $0.00156 |
Grade A, and why
hdhr-tuner-control 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 11d 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 — 115 lines — stays where its author put it; the contents beside it link to each section on GitHub.
HDHomeRun Tuner Control (hdhomerun_config protocol)
Speaks the same binary get/set protocol as the official hdhomerun_config CLI
(https://info.hdhomerun.com/info/hdhomerun_config) — TCP port 65001, TLV
framing, CRC32-checked packets. This is not the HTTP JSON API — none of
these item paths (/tuner<n>/status, vstatus, streaminfo, debug,
channel, target, program, filter) exist as HTTP endpoints; confirmed
by probing a live FLEX 4K (every one returned HTTP 404). They exist only over
this control protocol.
When to use
- Read raw signal metrics for a tuner (
ss/snq/seq/bps/pps). - Tune a physical RF channel/frequency directly (not via the HTTP stream URL).
- Set a PID filter, sub-channel program filter, or a UDP/RTP streaming target.
- Query/set the channelmap, IR target, lineup location, or
/sys/*firmware info. - Lock/unlock a tuner, or reboot the device (
restart).
When NOT to use
- Channel lineup, HTTP scan control, or building
/auto/v<ch>stream URLs →hdhr-http-api-ops. - DVR recording rules / record-engine →
hdhr-dvr-ops. - Finding the device's IP in the first place →
hdhr-discovery-ops. - A one-shot pass/fail read on several channels →
hdhr-doctor'ssignal_strengthcheck (it already drives this protocol for you).

|---|---|---|
HDHOMERUN_URL |
✅ | Used to derive the control-protocol IP (host portion) |
CONFIGTOOL |
optional | Toggle this tool domain (default enabled) |
Supported item paths are device/firmware-dependent — always call help
first on a device you haven't used before rather than assuming an item is
supported (e.g. vstatus and get-ting lineup/location both returned
"ERROR: unknown getset variable" on this package's own live FLEX 4K).

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.

hdhr-tuner-control is a skill published in the GitHub repository Knuckles-Team/hdhomerun-mcp (0 stars, last pushed 14d ago), licensed MIT. It adds 175 tokens to every session and 1,560 once invoked, about $0.0009 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.
