MCP + Semantic Recall

Your AI memory, inside every coding agent you already use.

dropdat now ships an MCP server. Wire it into Claude Code, Cursor, Cline, or Claude Desktop — and every session can recall, read, and save capsules across providers without copy-pasting context.

Install the MCP serverGet an API key

Five tools. One library.

The MCP server exposes exactly the surface an agent needs — and nothing it doesn't.

dropdat_recall

Hybrid semantic + keyword search across every capsule the user has saved. Vector cosine over OpenAI embeddings, fused with BM25 ranking via RRF. The agent can ask in any phrasing — matches surface even when the original capsule used different words.

dropdat_read

Fetch one capsule's full contents (every message, every version) by id. Pair with dropdat_recall to drill into a hit.

dropdat_list

Browse recent capsules, optionally filtered by tag. Use when the user wants to skim, not search.

dropdat_capsule

Save the current conversation as a new capsule. Call when the user says 'remember this' or at the end of a meaningful session.

dropdat_autocapsule

Save the FULL verbatim Claude Code session by reading the on-disk .jsonl transcript — no model reconstruction, every message preserved.

Powered by hybrid search

Recall by meaning, not just by word.

Every capsule is embedded automatically on save. When an agent calls dropdat_recall, the query embeds, runs vector + BM25 in one SQL pass, and returns ranked hits — even if the wording is entirely different.

Hybrid retrieval

Vector cosine + tsvector BM25, fused with Reciprocal Rank Fusion. Catches semantic matches and exact keywords in one query.

pgvector + HNSW

Embeddings live in your own Postgres. HNSW index over 1536-dim vectors keeps recall fast even at hundreds of thousands of capsules.

Auto-embedded on write

New capsules and edits embed in the background. No worker queue to operate, no separate vector DB to babysit.

Graceful fallback

No OPENAI_API_KEY set? Search degrades to BM25 only — your library stays searchable, just less smart.

Install in under a minute.

One npm package, one config block, any MCP-capable client. Source on GitHub.

  1. 01

    Issue an API key

    Open the API Keys page in your dashboard and create a key. Tokens are shown once and look like dk_live_….
  2. 02

    Install from npm

    # zero-install — runs the latest version on demand
npx -y @dropdat/mcp

# or pin a global install
npm install -g @dropdat/mcp

    Wire it into your client

    Claude Code (one-liner)
    claude mcp add dropdat \
  --env DROPDAT_API_KEY=dk_live_xxx \
  --env DROPDAT_API_BASE=https://dropdat.app \
  -- npx -y @dropdat/mcp
    Then /mcp inside Claude Code lists the new server and its five tools.
    Cursor, Cline, Claude Desktop, Continue
    {
  "mcpServers": {
    "dropdat": {
      "command": "npx",
      "args": ["-y", "@dropdat/mcp"],

        "DROPDAT_API_BASE": "https://dropdat.app"
      }
    }
  }
}
    Drop into the client’s MCP config file (e.g. ~/.cursor/mcp.json or claude_desktop_config.json) and restart the client.

    Talk to it

    • “What did we decide about auth last week? Check dropdat.”
    • “Save this conversation as a dropdat capsule titled ‘billing migration notes’.”
    • “List my recent dropdat capsules tagged ‘refactor’.”
