tribeRef MCP Server

Tribal memory infrastructure for tribeCast AI agents. This is an MCP (Model Context Protocol) server that provides persistent memory across Claude Code sessions.

What tribeRef Does

  1. Tribal Memory (ref_tribal_memory) - Query decisions, entities, schemas, and active tasks

  2. Session Context (ref_session_context) - Track tokens used, items retrieved, session state

  3. Log Artifacts (ref_log_artifact) - Write outputs back to tribal memory

  4. Log Decisions (log_decision) - Record architectural and strategic decisions

  5. Manage Entities (upsert_entity) - Create/update tracked objects (products, services, schemas)

  6. Task Management (create_task, log_completion) - Track work items for agents

{
  "mcpServers": {
    "triberef": {
      "command": "node",
      "args": ["/path/to/tribecast/packages/triberef-mcp/dist/index.cjs"],

Tools

ref_tribal_memory

Query tribal memory with deduplication (items already retrieved in session are filtered).

{

  "max_tokens": 5000
}

ref_session_context

Get current session state.

{}

Returns: session ID, tokens used/remaining, items retrieved counts.

ref_log_artifact

Log an artifact back to tribal memory.

{

  "name": "src/tools/tribal-memory.ts",
  "content": "..."
}

log_decision

Record an architectural decision.

{
  "topic": "Database architecture",
