Agentic Resource Registry

A self-hosted, Apache 2.0 registry for sharing coding agent resources. Formerly Observal.

Set up once, and let your coding agent use Agentic Resource Registry through observal-cli.

If you find Agentic Resource Registry useful, please consider giving it a star. It helps others discover the project and keeps development going.

Formerly Observal. Same code, same maintainers, same Apache 2.0 license. The CLI is still observal, and old Observal/Observal links redirect here.

What is Agentic Resource Registry and what does it solve?

Agentic Resource Registry is a self-hosted, Apache 2.0 registry for sharing coding agent resources across your organization. Every tech-forward organization today creates internal Skills, Agents files, MCP clients. Though the creation of these coding agent resources has been prolific, peer adoption and usage is sparse. Coding agent users today end up creating their own version of such resouces without reusing existing packages.

The cause is largely due to two problems:

1. Lack of a discoverability layer

   Organizations store their coding agent resources in siloed git repositories with little to no documentation. Users are not able to locate existing coding agent resources and this results in multiple developers creating the same/similar resources again.

2. Missing feedback loop

   Any software where usage patterns are not understood and the principle of user-centric development is violated tends to fade out. Such is the problem with development of MCP clients, Skills and Agent files. Authors publish and maintain these resources with little visibility into how they're actually used. Additionally, Coding agent failures don't trigger static error codes: they hallucinate or provide subtly incorrect answers. This leaves users clueless about what went wrong compounding the feedback problem.

Agentic Resource Registry solves this by providing a centralized discovery layer for coding agent resources alongside useful insights into usage patterns. It turns silent failures into actionable feedback, ensuring internal resources are continuously optimized for the people using them.

Agentic Resource Registry supports Claude Code, Cursor, Kiro, Pi, Copilot, Codex, OpenCode, and other tools.

Why teams use Agentic Resource Registry

• Centralize resources into one platform: Store Skills, MCP clients, hooks, prompts, agent files and sandboxes in one registry.
• Run a governed registry: Review submissions, approve internal agents, inspect version diffs, and give developers one trusted place to install from.
• Render across multiple Coding IDE/CLI: Generate the correct config for each supported harness instead of maintaining separate setup instructions for every harness.
• Let agents use each other: Every approved resource is discoverable over the open ARD standard, and a running agent can hand part of its task to another approved agent, whether it lives in the registry or is a remote A2A service.
• Learn what works: Use real adoption and session data to find which agents, tools, prompts, and workflows are helping teams.
• Replay sessions when needed: Use traces as evidence for debugging, review, audits, and deeper analysis.

Supported harnesses

One command to install any agent into any supported harness. The config files are generated per-harness automatically.

Where does observal fit in your modern enterprise infrastructure?

Quick Start

Agentic Resource Registry has two parts: a server (API + web UI + databases) you self-host, and a CLI you install on each developer machine.

1. Deploy the server

One-line install (requires Docker Engine ≥ 24.0 with Compose v2):

curl -fsSL https://raw.githubusercontent.com/AgenticResourceRegistry/AgenticResourceRegistry/main/install-server.sh | bash

This downloads a Docker Compose package, generates operator-owned secret files with restricted container-group access, binds published ports to loopback by default, pulls container images from GHCR, and starts the stack. With a terminal it runs guided setup; without a terminal the same command applies safe defaults automatically.

Deployment docs are linked directly from this README:

• Setup guide: fastest path from zero to a working stack
• Self-hosting overview: deployment models and operator docs
• Production deployment: hardened production topology
• Databases: Postgres, ClickHouse, migrations, retention
• Upgrades: safe upgrade and rollback flow
• Release verification: verify checksums, provenance, and signed tags
• Backup and restore: backup plan before upgrades

From source (for contributors):

git clone https://github.com/AgenticResourceRegistry/AgenticResourceRegistry.git && cd AgenticResourceRegistry
cp .env.example .env
make up

2. Install the CLI

Standalone binary (no Python required):

# macOS / Linux
curl -fsSL https://raw.githubusercontent.com/AgenticResourceRegistry/AgenticResourceRegistry/main/install.sh | bash

# Windows (PowerShell)
irm https://raw.githubusercontent.com/AgenticResourceRegistry/AgenticResourceRegistry/main/install.ps1 | iex

Connecting to an existing server? See the Setup guide.

Python (3.11+):

uv tool install observal-cli
# or: pipx install observal-cli

3. Connect your harness

observal auth login
observal doctor --patch

This authenticates with your server, detects your harness, installs telemetry hooks, starts capturing sessions automatically, and prepares it for agent installs and registry commands.

Once logged in, run /observal inside your harness and it takes the wheel. Pull agents, submit resources, browse the registry, run diagnostics:

/observal pull security-auditor
/observal scan
/observal doctor

Or just tell your agent what you want and it figures out the right commands.

How Agentic Resource Registry works

The registry is the distribution layer

The registry is where agents live. Admins review submissions, version diffs keep changes auditable, and one command installs an agent into any supported harness.

Insights close the loop

Real usage data flows back as reports: what's helping, what's getting in the way, and where to improve. Session traces provide the underlying evidence for debugging and auditing.

Coding agent resource registry

Browse and search by teamspace, publisher, category, or harness; each card shows its supported harnesses and pull count:

Build agent files in four steps (identity, behavior, components, review) with a live summary and draft readiness checks:

Component library with tabs for MCP servers, skills, hooks, prompts, and sandboxes:

Fork an approved release

Fork an agent or component into an independent draft in your personal namespace or an eligible teamspace. The source stays unchanged; agent forks retain pinned component references rather than copying components. Reviewers can compare the draft with its approved upstream using Diff vs upstream. Public approved direct forks appear on the source's Forks tab; private forks and unpublished drafts do not. Fork and customize guide.

Discovery and Delegation (ARD + A2A)

ARD: one search across everything approved. Agentic Resource Registry implements Agentic Resource Discovery (v0.91). Every approved agent, MCP server, skill, hook, prompt and sandbox is published as an ARD entry with a permanent urn:air: identifier, a public manifest at /.well-known/ard.json, and the spec's search API at /api/v1/ard/search. Results are ranked by relevance only; approval, visibility, harness support and whether the resource can be used right now are separate fields. The same visibility rules as the registry apply, so a team-private agent is only found by that team.

A2A: agents hand tasks to agents. Agentic Resource Registry speaks the Agent2Agent protocol (v1.0, with v0.3 compatibility). Every delegation is an A2A Task, whoever runs it:

• Registry agents run headless in a harness that supports it (Claude Code, Kiro, Cursor, Codex, OpenCode, Copilot CLI, Antigravity, Pi) inside a throwaway copy of your repository. Their answer comes back as a result, and any file changes come back as a patch that is never applied for you.
• Remote A2A agents (a service another team runs, built with any framework) are registered by their Agent Card URL, reviewed like any submission, and then called directly with the card the reviewer approved. Agentic Resource Registry never proxies the traffic or stores their credentials.

    T -- "remote agent" --> S["A2A service<br/>(approved Agent Card)"]
    H -- "answer + patch" --> A
    S -- "artifacts" --> A

Every agent you pull gets an observal-agents MCP server with four tools, find_agents, delegate, get_task and cancel_task, so it can do this without being told how. Delegation is limited to approved agents, stops after two levels, lets a delegated agent start at most three tasks of its own, and refuses loops. Each delegation is recorded against the calling session, so traces show which agents a session relied on.

Discover shows registry agents that can take a task and remote A2A agents side by side:

Delegate from any terminal or script. Here a remote A2A agent answers directly; a registry agent also hands back its file changes as a patch for you to review:

observal delegate find "review this branch for auth bugs"
observal delegate run acme/security-reviewer "Review src/auth on this branch for token leaks"
git apply ~/.observal/delegations/<task-id>/changes.patch     # only if you agree with it

observal registry a2a submit https://agents.acme.com --visibility team --team platform
observal discover inspect urn:air:agents.acme.com:a2a:incident-triage     # shows the card's Digest
observal registry a2a review urn:air:agents.acme.com:a2a:incident-triage --approve --digest sha256:...

Design decisions: ADR 0001 (ARD), ADR 0002 (A2A delegation). API: Discovery endpoints.

Review and Governance

Authors submit agent and component versions for review. Participants can inspect the submitted revision's redacted files and diffs, discuss changes in conversations, and submit approvals or change requests. Publishing is separate from approval: once the review policy and required checks are satisfied, a reviewer can publish the version, or policy can publish it automatically.

Open-source features

Audit logs, SAML SSO, SCIM provisioning, and the executive dashboard are included in the Apache-2.0 distribution.
