DecisionNode: MCP server, setup and security
DecisionNode is an open-source MCP server that lets an AI agent record development decisions and search them semantically across AI tools. Its repository has 83 stars and its last commit is from April 15, 2026 and it is licensed under MIT.
What DecisionNode does
According to its repository: “Record development decisions as structured JSON with Gemini embeddings and search them semantically from a local store shared across AI tools.”
An MCP server gives an AI agent extra tools it calls during the conversation: the agent reads their description, decides to use them and gets the result back. DecisionNode is listed under Memory and knowledge, a category of 250 servers in the directory, where it ranks #86 by stars.
Topics declared by the repository: cli, developer-tools, embeddings, gemini, rag, semantic-search.
Installing and connecting DecisionNode
No package or remote server is declared in the official MCP registry: you install it from source, following the repository README.
Like any MCP server, you declare it in your client's configuration (Claude Desktop, Claude Code, Cursor, VS Code, Codex…): a name, the command that starts it or its URL, and any environment variables. The client then starts it and lists its tools. Project language: TypeScript. Listed systems: macOS, Windows, Linux.
Security: what to check
An MCP server runs code with the rights you give it, and the model reads its tool descriptions: a malicious or compromised server can hijack the agent. Read the code, or pick a maintained and widely used server, before connecting it.
None of the risk signals we track (system access, secrets, missing licence, abandonment) applies to DecisionNode. That does not replace reading the code.
Good practice: grant only the rights needed (least privilege), require human approval for irreversible actions, and run the AI agent security check.
Project activity and maintenance
Created on April 5, 2026, the decisionnode/DecisionNode repository has 83 stars and 13 forks, with 0 open issues. It has more stars than 63% of the servers in the directory. Last change 6 months ago.
Stars measure attention, not quality: a recent, heavily promoted project can collect them fast, while a useful but niche server will have few.
Verdict
DecisionNode is still a modest project: read its code and compare it with the alternatives before using it.

No risk signal found (system access, secrets, licence, abandonment). As with any MCP server, keep rights minimal and read the code before sensitive use.
Is it an official server?
Nothing says so: it is a project published by decisionnode on GitHub. Check who maintains it before giving it access.
