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 | $0.00119 | $0.01150 |
| Opus 5 | $0.00060 | $0.00575 |
| Sonnet 5 | $0.00024 | $0.00230 |
| Haiku 4.5 | $0.00012 | $0.00115 |
Grade A, and why
mattermost-kg-ingestion 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 — 98 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Mattermost Knowledge-Graph Ingestion
Push Mattermost structure and conversation into the ONE epistemic-graph engine as
typed OWL nodes, message documents, and attachment blobs. Backed by
mattermost_mcp.kg_ingest / kg_media and federated by mattermost_mcp.ontology
(http://knuckles.team/kg/mattermost).
When to use
- Make a Mattermost workspace queryable in the KG (
:Team,:Channel,:Person). - Index a channel's conversation for semantic search (
:Documentmessages). - Store file attachments durably as content-addressed
:MediaAssetblobs. - Refresh an existing mirror (ingestion is idempotent MERGE by node id).
When NOT to use
- Interactive read/post of messages →
mattermost-channel-messaging. - Creating/administering teams and channels →
mattermost-team-administration. - Querying the graph after ingestion → the graph-os KG query tools, not this skill.
Prerequisites & environment
Connect via the mcp-client skill against the mattermost-mcp MCP server, plus a
reachable epistemic-graph engine (else the ingest legs no-op and return
{"ingested": null} — safe, but nothing is written).
| Variable | Required | Notes |
|---|---|---|
MATTERMOST_URL |
✅ | Server base URL (alias MATTERMOST_MCP_BASE_URL) |
MATTERMOST_TOKEN |
✅* | Personal-access / bot token |
MATTERMOST_MCP_USERNAME / MATTERMOST_MCP_PASSWORD |
✅* | Login fallback if no token |
MATTERMOST_MCP_SSL_VERIFY |
optional | TLS verification toggle |
*Provide either a token or username+password.
Tools & actions
Prefer the native Wire-First ingest tools — they list via the real client and push in
one call. Each returns {"listed": n, "ingested": {"nodes":…, "edges":…}}.
| Tool | What it ingests |
|---|---|
mattermost_ingest_teams |
teams → :Team nodes |
mattermost_ingest_channels |
a team's channels → :Channel (+ :inTeam) |
mattermost_ingest_users |
users → shared :Person / :Bot nodes |
mattermost_ingest_posts |
a channel's messages → :Document (+ :postedInChannel / :authoredBy / :repliesTo) |
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

mattermost-kg-ingestion is a skill published in the GitHub repository Knuckles-Team/mattermost-mcp (0 stars, last pushed 14d ago), licensed MIT. It adds 119 tokens to every session and 1,150 once invoked, about $0.0006 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.
