Noisegate
Differential-privacy gateway exposed as an MCP server: an untrusted agent can only ask aggregate queries, each answered with calibrated noise under a tracked privacy budget, with an attack gallery pinned in CI.
v1.0.0 released 2026-07-23; last push 2026-08-02; no activity since. (checked 2026-10-25)
In Agent guardrails
Where it stands apart
- Is it actively maintained? maintenance or slowing (5% of 21 others)
- How is it mainly sustained? individual side project, no revenue (25% of 20 others)
- Which shared standard or format does it mainly build on? Model Context Protocol (MCP) (19% of 21 others)
- What is the main thing it protects? outside systems and data (APIs, databases, money, private records) (19% of 21 others)
What it shares with most of the community
- How is the main thing licensed? permissive open source (MIT/Apache/BSD) (67% of 21 others)
- Can it run entirely on your own device or infrastructure, without the maker's servers? yes (76% of 21 others)
- Do you need an account to use it? no account (67% of 21 others)
- Who is it for? developers (90% of 21 others)
- What mainly decides whether an action is allowed? rules, policy, or boundaries written in advance (57% of 21 others)
- If the guard itself breaks, is missing, or cannot decide, what happens by default? fails closed: the action does not run (71% of 17 others)
- Which agents does it work with? any agent or process (not limited to a named list) (71% of 21 others)
- In the default setup, where does the agent's work actually execute? directly on the host machine, as usual (52% of 21 others)
- Does it control the agent's outbound network access? no (56% of 16 others)
- What is it mainly for? adding checkpoints, review, or evidence (52% of 21 others)
- Is enforcement kept out of the agent's reach? yes, enforced in code or infrastructure the agent cannot change (95% of 21 others)
