What is the Toolkit?

CORE’s Toolkit is a unified actions layer — 50+ app integrations exposed through a single MCP endpoint. Any MCP-compatible agent can use it: Claude Code, Cursor, Windsurf, CORE’s own Agent, or your custom agents. Connect an app once on the CORE Dashboard, and every connected agent gets access. No need to build or maintain separate tool integrations per agent.

​
Why Use CORE’s Toolkit?

  1. One endpoint, all your apps: Instead of configuring a separate MCP server for GitHub, another for Slack, another for Calendar — connect CORE once and get everything through a single endpoint. One connection, 15+ integrations.
  2. On-demand tool loading: CORE doesn’t dump all tools into your agent’s context. When an agent needs to act, it describes what it wants to do. CORE filters and returns only the 1-3 relevant tools with their schemas. This saves thousands of tokens and keeps your agent focused.
  3. Works with any MCP-compatible agent: Claude Code, Cursor, Windsurf, your custom agents — anything that speaks MCP gets the full toolkit without extra setup.

​
How It Works

​
Connect apps on the CORE Dashboard

Connect each integration securelt and authenticates via OAuth or API keys

​
Agent describes intent

When a user ask a question, agent sends an intent query e.g “send a slack message” and gets back only the relevant tool schemas.

​
Agent executes

Agent then calls the action/tools with the right parameters, CORE handles the rest 
You: "Create a GitHub issue for the auth bug and message Sarah on Slack"

Agent:
→ Calls get_integration_actions("create github issue") → gets create_issue schema
→ Calls execute_integration_action(create_issue, {title, body, repo})
→ Calls get_integration_actions("send slack message") → gets send_message schema
→ Calls execute_integration_action(send_message, {channel, text})

​
Connecting via MCP

All toolkit actions are exposed through a single MCP endpoint. Instead of configuring separate MCP servers per app, you connect CORE once. Base MCP URL: 
https://app.getcore.me/api/v1/mcp

Traditional:  Your AI Tool → GitHub MCP Server (auth required)
              Your AI Tool → Linear MCP Server (auth required)
              Your AI Tool → Slack MCP Server (auth required)

With CORE:    Your AI Tool → CORE MCP Endpoint → All Integrations (pre-authenticated)
See MCP Configuration for query parameters and Authentication for OAuth and API key setup.

​
Webhooks & Triggers

CORE also supports proactive automation. When events happen in your connected apps e.g new email, GitHub issue created, Slack message in a channel, CORE can automatically respond based on your configured triggers. Each integration page below lists its available webhook triggers alongside its action tools.
