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 | $0.00164 | $0.01280 |
| Opus 5 | $0.00082 | $0.00640 |
| Sonnet 5 | $0.00033 | $0.00256 |
| Haiku 4.5 | $0.00016 | $0.00128 |
Grade A, and why
hdhr-http-api-ops 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 — 106 lines — stays where its author put it; the contents beside it link to each section on GitHub.
HDHomeRun HTTP API Operations
Direct access to the HDHomeRun HTTP JSON API (https://info.hdhomerun.com/info/http_api) for a device at a known URL: device identity, channel lineup, and scan control.
When to use
- Fetch the channel lineup (
lineup.json) or check scan progress (lineup_status.json). - Start or abort a channel scan.
- Get device identity/firmware/tuner-count (
discover.json). - Build a live-stream URL for a virtual channel or RF frequency.
When NOT to use
- You don't know the device's IP/hostname yet →
hdhr-discovery-opsfirst. - DVR recording rules or record-engine calls →
hdhr-dvr-ops. - Per-tuner signal strength / raw get-set (
status,vstatus,streaminfo,channel,filter,target,program) →hdhr-tuner-control(a different, binary wire protocol on port 65001 — these items are not HTTP endpoints; confirmed 404 against a real FLEX 4K). - A single pass/fail health report →
hdhr-doctor(composes this skill).
Prerequisites & environment
Connect via the mcp-client skill against the hdhomerun-mcp MCP server.

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-http-api-ops is a skill published in the GitHub repository Knuckles-Team/hdhomerun-mcp (0 stars, last pushed 12d ago), licensed MIT. It adds 164 tokens to every session and 1,280 once invoked, about $0.0008 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.
