Why AgentNode
Stop Searching. Start Resolving.
When your agent needs PDF extraction, web search, or email capabilities, you should not be browsing through 500,000 PyPI packages hoping to find something that works with your framework. AgentNode is the verified, buildable, importable capability registry built specifically for AI agent developers. Every package is automatically verified on publish — packages are tested and scored for quality.
The Problem with the Status Quo
AI agent developers deserve better than general-purpose package registries.
500K+ packages. No AI-specific search, no permission model, no framework compatibility metadata, no trust verification. Every package has a different API surface. You have to read source code just to know if a package is safe.
Same fragmentation, different runtime. Thousands of abandoned packages, no way to filter by agent compatibility, no security policy enforcement. You are on your own.
Weeks of development per capability. You own the maintenance burden, the security responsibility, and every edge case. PDF parsing alone can take a team a sprint to get right.
Framework lock-in, proprietary formats, limited discovery. Most require you to adopt an entire platform just to get access to a handful of tools.
How AgentNode Is Different
Seven design decisions that make AgentNode the right choice for AI agent developers.
Capability-First Search
Describe what your agent needs, not what package to install.
You don't search by package name. You describe a capability gap — "pdf extraction", "email sending", "web search" — and the resolution engine returns ranked, verified results. Scoring is weighted: capability match (40%), framework compatibility (20%), runtime fit (15%), trust level (15%), permissions safety (10%). Your agent gets the best tool for the job, every time.
Verified on Publish
Every package is tested before it reaches your agent.
Every pack goes through a 4-step verification pipeline on publish: Install (can it be pip-installed?), Import (does the module load?), Smoke Test (does the entry point execute?), and Unit Tests (do the author's tests pass?). If install or import fails, the pack is auto-quarantined and never reaches the registry. Smoke or test issues get transparent warning badges so you can make an informed decision. No other registry does this. PyPI lists packages that fail to install. npm has abandoned packages with zero warning. AgentNode guarantees: packages are tested on publish and scored for quality.
One Format, Every Framework
Per-tool entrypoints. Typed schemas. No framework lock-in.
ANP v0.2 introduces per-tool entrypoints: a single pack can export multiple tools, each individually addressable via load_tool(). Every tool has typed JSON Schema input and output, so your agent knows exactly what to pass and what to expect. It works with LangChain, CrewAI, or vanilla Python. Write your agent in whatever framework you prefer — the packs adapt to you, not the other way around.
Programmatic Resolution
Your agent resolves its own capability gaps. No human needed.
The SDK enables fully autonomous capability resolution. Your agent calls client.resolve(["pdf_extraction", "web_search"]) and gets back ranked results it can evaluate and install programmatically. This is the foundation for self-improving agents — they identify what they cannot do, find the right tool, verify it meets policy, and install it. All through code.
Policy Enforcement
Set the rules. The engine enforces them.
Define policies like "only trusted publishers", "no network access", "no code execution", or "only packs compatible with LangChain". The resolution engine filters automatically — non-compliant packages never surface. This is critical for production deployments where agents must operate within strict security boundaries.
Fully Open Source
MIT-licensed tools. Open format. No vendor lock-in.
The CLI, SDK, and ANP pack format are MIT-licensed and developed in the open on GitHub. Every pack is inspectable — you see the manifest, permissions, and source before you install. The registry is community-driven: anyone can publish, the best tools earn trust through usage and review. You are never locked into AgentNode — packs are standard Python that works anywhere.
Build or Import — Zero Friction
Go from idea to published package in minutes, not days.
Two paths to publishing, both frictionless. The AI Builder lets you describe what your agent should do in plain language — it generates a complete ANP package with manifest, code scaffold, and typed schemas, ready to publish. The Import tool takes existing LangChain, MCP, OpenAI, or CrewAI tool code and automatically converts it to ANP v0.2. No rewrite required. Paste your code, get a publish-ready package back.

The Developer Experience
From capability gap to working code in under a minute.
pip install agentnode-sdkfrom agentnode_sdk import AgentNodeClient
from agentnode_sdk.installer import load_tool
client = AgentNodeClient()
# Resolve and install
client.resolve_and_install(["pdf_extraction"])
# Load and use — typed input/output
extract = load_tool("pdf-reader-pack")
result = extract({"file_path": "quarterly-report.pdf"})
print(result["pages"])from openai import OpenAI
from agentnode_sdk import AgentNodeRuntime
# Or let the LLM handle everything
result = AgentNodeRuntime().run(

Open Source. Open Format. Open Registry.
AgentNode is built in the open. The SDK, CLI, and pack format are MIT-licensed. The registry is community-driven. You are never locked in.
MIT-licensed SDK & CLI
The tools you build with are fully open source under MIT. No vendor lock-in, no proprietary dependencies. Fork it, extend it, self-host it — your choice.
Open ANP format
The AgentNode Package format is an open specification. Every manifest is human-readable YAML. You can inspect exactly what a pack does, what it accesses, and how it works — before you install it.
Transparent by default
Every pack links to its source repository. Read the code, audit the dependencies, verify the build. No black boxes, no hidden network calls, no surprises in production.
Community-driven registry
Anyone can publish packs. The AI Builder and Import tool make publishing even easier — describe a capability or paste existing code and get a publish-ready package. The registry grows because developers contribute what they build — not because a company decides what gets listed. The best tools rise through trust levels and community usage.
No walled garden
Packs work outside AgentNode too. The code is standard Python with a standard interface. If you ever leave the platform, your tools still work. We earn your usage, not lock it in.
Public roadmap & governance
Feature development happens in the open on GitHub. File issues, propose changes, contribute code. The platform belongs to the community that builds on it.
Built for Teams and Production
AgentNode works the way your team already works.
MCP Integration
Available nowExpose AgentNode packs as MCP tools for Claude Code, Cursor, and any MCP-compatible client. Your team searches, resolves, and installs capabilities without leaving their editor. The MCP adapter wraps the full platform API — search, resolve, explain, and capability browsing.
Policy Controls
Available nowEnforce organization-wide policies on which packs can be installed. Restrict by trust level, permission scope, publisher, or framework. The resolution engine filters non-compliant packages automatically — your agents stay within bounds.
Python — for agents & apps
Available nowFull programmatic access via agentnode-sdk. Search, resolve, check policies, and manage installations from Python. Supports async operations and API key authentication for CI/CD pipelines and automated workflows.
GitHub Action
Available nowAutomate pack publishing from your CI/CD pipeline with agentnode/publish@v1. Validates manifests, runs security scanning, and publishes on release. Supports dry-run mode for validation-only workflows.
AI Builder
Available nowDescribe a capability in plain language and get a production-ready ANP package — manifest, code scaffold, and typed schemas. No boilerplate.
Import from Any Framework
Available nowPaste existing LangChain, MCP, OpenAI, or CrewAI tool code and get an ANP package back. Zero rewrite required.
Trust You Can Verify
Every pack in the registry has a clear, auditable trust level.
Two independent quality signals: Every pack has both a Trust Level (who built it?) and a Verification Badge (passed / failed / pending — does it actually work?). Trust tells you about the publisher. Verification tells you about the code.
