Fullmakt

What it does

Fullmakt is a credential broker for AI agents. Your agent gets a short-lived, scoped token; your real API keys stay in the vault and get injected server-side, only after policy allows the call. Unlike token vaults that hand the credential back to the agent and exit, Fullmakt stays in-path — so every call lands in a tamper-proof, cryptographically chained audit log. MCP & OAuth 2.1 native, policy engine with human approval holds, usage-based pricing, free no-card sandbox.

Issue, test, verify and audit credentials for AI agents. Give your agents scoped, revocable access to APIs — with full visibility into every call.

Issue scoped, short-lived credentials to your AI agents. Test their access, verify their behavior, and audit every call — from one control plane. Fullmakt is a credential broker for AI agents. It issues scoped, short-lived credentials to your agents on demand, verifies their access on every request, and records a tamper-proof audit of every call — so your secrets never reach the model and every action stays attributable. If you are shopping by category: this is AI agent access control — the layer people also look for as secrets management for AI agents, non-human (machine) identity, or MCP server security. Fullmakt is not a replacement for your identity provider or your secret store. It…from fullmakt.ai

  TrueFoundry AI GatewayDec 2025 · truefoundry.com · ▲315

  Many teams connecting LLMs to external tools eventually encounter the same architectural issue: as more tools and agents are added, the integration pattern becomes an N×M mesh of direct connections. Each agent implements its own auth, retries, rate limiting, and logging; each tool needs credentials distributed to multiple places and observability becomes fragmented. We built LLM gateway with this goal to provide a single place to manage authentication, authorization, routing, and observability for MCP servers, with a path toward a more general agent-gateway architecture in the future.

  Agent Vault – Open-source credential proxy and vault for agentsApr 2026 · github.com · ▲156

  Hey HN! Today we're launching Agent Vault - an open source HTTP credential proxy and vault for AI agents. Repo is at https://github.com/Infisical/agent-vault, and there's an in-depth description at https://infisical.com/blog/agent-vault-the-open-source-crede.... We built Agent Vault in response to a question that been plaguing the industry: How do we give agents secure access to services without them reading any secrets? Most teams building agents have run into this exact problem: They build an agent or agentic system and come to realize at some point…

  Hi HN, At Imbue, we’ve been following the rapid developments in the agent landscape and noticed that the way agents interact with third-party services on users’ behalf often leaves a lot to be desired. Integrations are ad hoc, complicated, context-heavy, and either unfriendly to non-technical users or tied to a lock-in of some sort. We‘re experimenting with a command-line tool, Latchkey, that could be used by local agents targeted at non-technical users while avoiding remote intermediaries. As far as we know, this is the only existing approach at the intersection of these two goals. Core…

  Clipto MCP▲655

  Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

  Simple algorithm and color space to generate diverse skin tones▲627

  Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
