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 | $0.00069 | $0.00902 |
| Opus 5 | $0.00034 | $0.00451 |
| Sonnet 5 | $0.00014 | $0.00180 |
| Haiku 4.5 | $0.00007 | $0.00090 |
Grade A, and why
smcp-status 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 7d 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 — 76 lines — stays where its author put it; the contents beside it link to each section on GitHub.
subagent-mcp Status
When triggered, call the get_status MCP tool and present its live session
state. Use only what get_status returns. Do not read state files, guess,
or cache: the numbers come from the running MCP server's in-memory state, so a
fresh call each time is the single source of truth. If the get_status tool is
not available, say the subagent-mcp MCP server is not connected in this session
and point the user at the /smcp:doctor skill.
Data source
get_status returns a JSON object with these fields:
providers_loaded- array of provider names parsed fromproviders.jsoncat server start.agent_count- number of agents launched since this server process started.session_start_time- ISO timestamp of the MCP server process boot (may be null), used to compute uptime.last_routing_decisions- array of{ category, provider, timestamp, elapsed_ms }, most recent last, capped at the last 10.swarm- agentic-swarm session snapshot:{ active, current_stage, stage_name, pin_active, pin_expires_at }. Whenactiveis false all other swarm fields are null or false.
Presentation (E1-standardized)
Render uniform, one-item-per-line, plain-ASCII output. No smart quotes, no emoji, no tables. Use this exact shape:
subagent-mcp status
providers_loaded (N): name1, name2, ...
agent_count: K (since session start)
last routing decisions (most recent last):
1. category=<category> provider=<provider> elapsed_ms=<n>
2. category=<category> provider=<provider> elapsed_ms=<n>
3. category=<category> provider=<provider> elapsed_ms=<n>
Rules for filling it in:
providers_loaded: print the count then the comma-separated names. If the array is empty, printproviders_loaded (0): none loaded. If you can determine reachability (for example from a recent/smcp:doctorrun in this conversation), add a short parenthetical note per provider such as(reachable)or(unreachable); otherwise omit the note rather than guessing -get_statusalone does not probe reachability.agent_count: print the integer verbatim. Whensession_start_timeis present you may add uptime, for exampleagent_count: 4 (since session start, up 12m); if it is null, just print the count.- last routing decisions: show the last 3 entries from
last_routing_decisions(the 3 most recent). Number them 1-3 with the oldest of the three first and the newest last. If fewer than 3 exist, show what is there. If the array is empty, printlast routing decisions: none yet.
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.

smcp-status is a skill published in the GitHub repository Heretyc/subagent-mcp (3 stars, last pushed 2d ago), licensed Apache-2.0. It adds 69 tokens to every session and 902 once invoked, about $0.0003 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.
