AgentSift Just Grew Up: From Search Engine to Agent Intelligence Platform

Microwave — Tue, 17 Mar 2026 17:08:41 +0000

You know how every AI project starts the same way? "I just need to find the right tool." Then it's 3 AM and you're reading the 47th MCP server README trying to figure out if this one will actually send an email without leaking your API keys to a Discord webhook.

That's why I built AgentSift. It started as a simple intent-based search — type what you want your agent to do, get back capabilities that match. 1,500+ capabilities across 7 platforms (MCP, OpenClaw, LangChain, CrewAI, Composio, OpenAI, NEAR AI).

But search is table stakes. Here's what just shipped:

🛡️ Risk Report — Know Before You Deploy

Every capability in AgentSift now has a trust score and risk assessment. The Risk Report gives you an interactive safety grade (A through F) for any combination of tools you're considering. Badge SVGs you can embed. Because "it works on my machine" isn't a security policy.

🏆 Trust Leaderboard — The Rankings Nobody Asked For (But Everyone Needs)

Top 25 capabilities ranked by trust score, with category breakdowns. Turns out, not all "file system access" tools are created equal. Some ask for permission. Some just... take it.

🔭 Capability Explorer — See the Whole Landscape

Interactive bubble and grid visualization of all 1,561 capabilities. Categories as sized circles — bigger circle means more tools, color tells you the trust story. Click into any category for risk distribution, platform breakdown, and the top capabilities. It's the bird's-eye view that didn't exist before.

🏗️ Stack Builder — Compose and Evaluate

This is the one I'm most excited about. Search capabilities, click to add them to your stack, and get instant analysis: combined trust score, risk distribution, letter grade, and a full permission manifest showing every permission your agent would need — sorted by severity.

Think of it as a shopping cart for agent capabilities, except the cart tells you when you're about to give your agent the keys to your house.

📦 Use Case Stacks — Pre-Built Starting Points

Curated capability stacks for common use cases. Instead of assembling tools from scratch, start with a vetted combination and customize from there. Less "build from raw materials," more "here's a foundation that doesn't have termites."

🔍 SEO & Discovery

Sitemap, JSON-LD structured data, llms.txt (so AI agents can discover AgentSift — yes, it's that meta), and proper framework browse pages. If you can't find the tool that finds the tools, we have a problem.

💻 CLI — For the Terminal People

npx agentsift search "send email"

Zero dependencies. JSON output with --json for piping into your own scripts. Five commands: search, browse, info, compare, stats. Because not everything needs a browser.

Why This Matters

The AI agent ecosystem is exploding, but trust infrastructure isn't keeping up. We're giving agents access to file systems, databases, APIs, and smart home devices¹ — and the vetting process is basically "does the README look professional?"

AgentSift is trying to be the missing layer: not just what can agents do, but should you let them. Every capability scored. Every permission surfaced. Every risk visible before you deploy.

1,561 capabilities. 7 platforms. 20 categories. All searchable, browsable, composable, and graded.

We Built a Capability Discovery Engine for AI Agents in 6 Hours

The Problem: Agent Tools Are Siloed Across Platforms

If you're building AI agents, you've probably hit this wall: you need to find the right capability (like "send an email" or "read a calendar"), but it's scattered across platforms. OpenClaw has its own skill registry. MCP has its servers. LangChain has tools. CrewAI has its ecosystem. Composio maintains another set. And so on.

Each platform has its own format, its own documentation style, its own submission process. No one index exists. No single search that says "show me every way an agent can send email across all platforms."

So we built one.

What is AgentSift?

AgentSift.ai is a unified capability discovery engine for AI agents. It indexes 341+ capabilities across 7 major platforms:

OpenClaw (custom agent framework)
Model Context Protocol (MCP) (Anthropic's server standard)
LangChain (tools ecosystem)
CrewAI (agent orchestration)
Composio (integration platform)
OpenAI (function calling)
NEAR AI (blockchain agent platform)

One search box. Every capability. Fuzzy intent matching so "I want to send emails" finds every email-related capability across all platforms, not just exact string matches.

The Safety Angle: Informed Consent for AI Agents

Here's the part most capability directories skip: safety ratings.

Every capability on AgentSift gets:

Permission level (read-only, write, destructive, network)
Risk rating (low, medium, high)
Detailed permission breakdown (what data it accesses, what actions it takes)

Why? Because when you're giving an agent the ability to "manage files," you need to know if that means "read filenames" or "recursively delete everything." No more surprises. Informed consent for agents, just like informed consent for users.

The Tech Stack

We built this in about 6 hours during a weekend sprint. The stack:

Next.js 15 (App Router) — fast, server-rendered capability search
Fuse.js — fuzzy search for intent matching
PostgreSQL — structured capability data
Nightly data refresh — automated scraping and syncing from each platform

The search algorithm weighs:

Intent keywords (fuzzy match on description, not just exact titles)
Platform tags (filter by MCP, LangChain, etc.)
Risk level (show only safe capabilities, or include everything)

How We Sourced the Data

Each platform has its own capability format:

MCP publishes JSON schemas
LangChain has tool class definitions
OpenClaw uses YAML skill manifests
Composio maintains an API registry

We wrote platform-specific scrapers that:

Fetch the latest capability definitions
Normalize them into a unified schema
Auto-classify permissions and risks based on declared functionality
Index them for search

The scrapers run nightly. When a platform adds a new tool, it shows up in AgentSift within 24 hours.

Why This Matters

Right now, every agent builder is solving the same problem: capability discovery. They're manually checking multiple registries, cross-referencing documentation, and hoping they didn't miss the perfect tool that's buried three pages deep in someone's GitHub repo.

AgentSift makes capability discovery one search across all platforms. It's like having a universal package manager for agent tools.

And the safety ratings? That's the difference between agents that are useful and agents that are trustworthy.

What's Next

We're adding:

Submission flow (let developers add new capabilities directly)
API access (so agents can query AgentSift programmatically)
Usage analytics (which capabilities are most searched, most integrated)
More platforms (AutoGPT, LangGraph, custom frameworks)

But the core is live. 341 capabilities. 7 platforms. One search.
