MCP tools

Once kontxt is registered with your MCP client, these tools are available by name. Your AI client calls them automatically — you don’t invoke them directly.

​
get_relevant_context

Semantic search over your vault. Returns the top-ranked memories for the active task. When it’s called: At the start of most sessions, or when the host determines context would be useful. Returns: An ordered list of memories ranked by relevance to the current task. 
{
  "tool": "get_relevant_context",
  "input": {
    "query": "auth implementation preferences",
    "limit": 5
  }
}

​
store_memory

Write a durable memory from the current conversation. When it’s called: When you or the AI identifies something worth preserving — a decision, a preference, a fact. 
{
  "tool": "store_memory",
  "input": {
    "content": "Uses JWT with 7-day expiry for API auth",
    "type": "decision",
    "importance": 0.9
  }
}

​
store_conversation_summary

Summarize and store a full thread as a single memory entry. When it’s called: At the end of a long session to compress the context into something retrievable later. 
{
  "tool": "store_conversation_summary",
  "input": {
    "summary": "Designed the memory relevance scoring system. Decided on 4-signal ranking: semantic similarity, recency, frequency, importance.",
    "session_id": "abc123"
  }
}

​
get_user_profile

Returns preferences and facts grouped for grounding. Used to establish who you are at the start of a session. When it’s called: When the host needs a baseline context snapshot — typically on first message. Returns: A structured profile derived from your stored preferences and facts.

​
auto_capture

Optional passive capture of significant context from the current session. When it’s called: Only when explicitly enabled. Monitors the session for noteworthy content and stores it without requiring manual store_memory calls.
auto_capture is opt-in and disabled by default. Enable it only if you want fully passive memory capture.
