MCP server for Dakera AI. Gives any MCP-compatible AI agent persistent, queryable memory — with smart token management built in.

Works with Claude, Claude Code, and any MCP-compatible framework.

Part of Dakera AI — the memory engine for AI agents.

The Dakera memory engine scores 88.2% on LoCoMo (1,540 questions, standard eval) — benchmark details


Architecture: 14 core tools + on-demand discovery

Starting every agent session with 60+ tool schemas wastes ~15K tokens before you write a single message. dakera-mcp solves this with hybrid tool exposure:

  • 14 tools loaded by default — the 12 highest-frequency memory operations + 2 meta-discovery tools
  • On-demand expansion — use dakera_discover_tools and dakera_load_tools to fetch additional tool schemas only when you need them

Default tool set (core profile)

ToolPurpose
dakera_storeStore a memory with importance, tags, and type
dakera_recallSemantic recall by query text
dakera_searchAdvanced memory search with tag/type filters
dakera_session_startStart a session to group related memories
dakera_session_endEnd a session with optional summary
dakera_batch_recallBulk filter-based recall (by tags, importance, time)
dakera_forgetDelete specific memories by ID
dakera_hybrid_searchCombined vector + BM25 search
dakera_fulltext_searchBM25 full-text search
dakera_knowledge_graphBuild a knowledge graph from a seed memory
dakera_extractExtract entities and structure from free-form text
dakera_batch_forgetBulk delete by tags, type, or time range
dakera_discover_toolsSearch the full tool catalog by keyword or tier
dakera_load_toolsLoad full schemas for specific tools on demand

Profiles & token cost

ProfileTools~TokensHow to enable
core14~2,964Default — always loaded
admin32~5,975DAKERA_MCP_PROFILE=admin
power69~13,205DAKERA_MCP_PROFILE=power
all87~16,212DAKERA_MCP_PROFILE=all

Accessing additional tools

# In your agent: discover what's available
dakera_discover_tools(tier="power")
→ returns names + descriptions, no schemas loaded

# Load schemas for the tools you want
dakera_load_tools(tools=["dakera_consolidate", "dakera_agent_stats"])
→ returns full inputSchema for each tool

Profile selection

The profile controls which tools appear in tools/list. Three ways to set it:

1. Per-request (in tools/list params):

{"profile": "power"}

2. Environment variable (applies to all requests):

DAKERA_MCP_PROFILE=power

3. Default: core (14 tools, ~2,964 tokens)


Run Dakera

The MCP server connects to a Dakera memory server. You need one running first:

docker run -d \
  --name dakera \
  -p 3300:3000 \
  -e DAKERA_ROOT_API_KEY=dk-mykey \
  ghcr.io/dakera-ai/dakera:latest

For persistent storage (recommended):

curl -sSfL https://raw.githubusercontent.com/Dakera-AI/dakera-deploy/main/docker-compose.yml \
  -o docker-compose.yml
DAKERA_API_KEY=dk-mykey docker compose up -d

curl http://localhost:3000/health  # → {"status":"ok"}

Connect

Add to .mcp.json (Claude Code) or claude_desktop_config.json (Claude Desktop):

{
  "mcpServers": {
    "dakera": {
      "command": "dakera-mcp",
      "env": {
        "DAKERA_API_URL": "http://localhost:3300",
        "DAKERA_API_KEY": "your-key"
      }
    }
  }
}

To start with the power profile (exposes 68 tools):

{
  "mcpServers": {
    "dakera": {
      "command": "dakera-mcp",
      "env": {
        "DAKERA_API_URL": "http://localhost:3300",
        "DAKERA_API_KEY": "your-key",
        "DAKERA_MCP_PROFILE": "power"
      }
    }
  }
}

Why This Exists

AI agents forget everything when the session ends. Dakera fixes that. This MCP server gives your agent a persistent memory layer with zero infrastructure overhead — point it at a Dakera instance and it works.

The 14-tool default keeps your context window lean. The meta-tools let you expand on demand when you need advanced operations like bulk vector upsert, knowledge graph traversal, or memory federation.
