powernode

A set of operations for searching, exploring, reasoning over, and updating a shared knowledge system through MCP tools. MCP is a standard way for an AI agent to use external tools.

In plain words
What is it for?
It is for searching knowledge graphs, examining connected items, extracting information into the graph, managing shared entries, and querying or recording learned information.
Why use it?
It gives the agent defined ways to find existing knowledge, understand relationships, and save new information instead of treating every conversation as isolated.

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.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

powernode 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 yesterday.

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.

Powernode Platform Operations

Interact with the Powernode knowledge ecosystem and skill management via MCP tools.

Routing

Based on the user's request, determine the domain and use the appropriate MCP tool:

Knowledge Graph

  • Search: platform.search_knowledge_graph (action=search, query, mode=hybrid/vector/keyword/graph)
  • Reason: platform.reason_knowledge_graph (action=reason, query, max_hops)
  • Explore: platform.get_graph_node, platform.list_graph_nodes, platform.get_graph_neighbors
  • Extract: platform.extract_to_knowledge_graph (action=extract, text — runs LLM extraction pipeline to create nodes/edges)
  • Stats: platform.graph_statistics

Shared Knowledge

  • Search: platform.search_knowledge (action=search_knowledge, query)
  • Create: platform.create_knowledge (action=create_knowledge, title, content, content_type, tags)
  • Update: platform.update_knowledge (action=update_knowledge, entry_id, content, tags)
  • Promote: platform.promote_knowledge (action=promote_knowledge, entry_id)

Compound Learnings

  • Query: platform.query_learnings (action=query_learnings, query, category, scope)
  • Create: platform.create_learning (action=create_learning, title, content, category)
  • Reinforce: platform.reinforce_learning (action=reinforce_learning, learning_id)
  • Metrics: platform.learning_metrics

Skills

  • List/Search: platform.list_skills (action=list_skills, search, category, status)
  • Get: platform.get_skill (action=get_skill, skill_id)
  • Discover: platform.discover_skills (action=discover_skills, task_context)
  • Create: platform.create_skill (action=create_skill, name, description, category, system_prompt, commands, tags)
  • Update: platform.update_skill (action=update_skill, skill_id, + fields to change)
  • Toggle: platform.toggle_skill (action=toggle_skill, skill_id, enabled)
  • Delete: platform.delete_skill (action=delete_skill, skill_id) — cannot delete system skills
  • Health: platform.skill_health, platform.skill_metrics

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.

powernode is a skill published in the GitHub repository nodealchemy/powernode-platform (2 stars, last pushed 3d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 586 tokens. 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.
