Agentic search over your Dewey document collections from any MCP-compatible client.
Most developer tooling work still happens through a UI a human drives. Dewey MCP server moves it into the conversation instead. Agentic search over your Dewey document collections from any MCP-compatible client.
Add to your claude_desktop_config.json (or equivalent MCP client config):
The server publishes 1 tool. What each one is for:
Deduplication — Non-canonical documents are excluded from retrieval and contradiction detection. Requires enableDeduplication: true on the collection (set viaThe server ships on npm as @meetdewey/mcp, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.
Configuration is passed through the environment: DEWEY_API_KEY, DEWEY_COLLECTION_ID, DEWEY_API_URL. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Dewey's toolset — Deduplication — is a fair guide to whether it matches your workflow. It is maintained by com.meetdewey; worth a glance at recent repository activity before you build anything load-bearing on it.
We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.
