The control plane
for your AI agents

Connect your tools. Pillar adds the reasoning engine, knowledge pipeline, and dashboard — then deploys to Slack, your app, Discord, MCP, and whatever's next. Open source.

The Pillar way

ToolsBring your MCP server, point at your OpenAPI spec, or define tools in code. All three feed into the same agent.
KnowledgeCrawl your docs, connect content sources, auto-index. Every agent searches the same knowledge base.
Reasoning EnginePlans, selects tools, chains multi-step actions. You bring the APIs — Pillar orchestrates.
Control PlaneDashboard for agent config, analytics, conversations, and identity. One place to manage everything.
ChannelsDeploys to Slack, Discord, your app, MCP, CLI — and whatever's next. Change once, update everywhere.

Bring Your Tools

Point Pillar at your OpenAPI spec, connect your MCP server, or define tools in code. All three feed into the same agent.

Managed Knowledge

We crawl your docs and integrate with your content sources. Add a source and every agent gets it automatically.

Pick and Choose Per Agent

Create an internal Slack agent, a customer-facing copilot, a Cursor agent. Configure exactly which tools and knowledge each one sees — all from the dashboard.

Updates Happen Everywhere

Change a tool, update your docs, add a knowledge source. Every agent that uses it gets the update — no redeployment per channel.

[03] EVERY CHANNEL

One brain, every surface

In-app copilot runs in the user's browser. Slack and Discord call your backend APIs. MCP exposes tools to any client. One agent brain powers all of them.

In-App Copilot

Runs in the user's browser with their session — same auth, zero latency. Actions register as WebMCP tools. When navigator.modelContext ships, your app is already wired.

Slack & Discord

Agents call your backend APIs directly — native to each platform. Slack threads, Discord channels, same tools and knowledge.

MCP Compatible

Expose your tools to any MCP client, or connect your existing MCP server as a tool source. Pillar speaks the protocol natively.

One Dashboard

Manage conversations, analytics, and agent config across every channel — one control plane for all of them.

[05] EASY TO DEPLOY

Deploy in minutes,
not days

Add your tool sources in the dashboard — OpenAPI spec, MCP server URL, or SDK-defined tools. Connect your knowledge sources, pick which tools each agent gets.

We've seen companies deploy a Slack app in a day. Updates happen everywhere — no per-channel redeployment.
