ConfigCat MCP server for AI agents and assistants

Securely connect your AI agents and chatbots (Claude, ChatGPT, Cursor, etc) with ConfigCat MCP or direct API to manage feature flags, inspect rollout rules, update environments, and review configuration settings through natural language.

TOOLS

Supported Tools

Every ConfigCat action and event your agent gets out of the box.

Create Flag or Setting

Create a feature flag or typed setting in a Config.

Delete Flag or Setting

Permanently delete one ConfigCat feature flag or setting by ID.

Get Product Context

Return a ConfigCat Product's configs, environments, segments, and tags, including the identifiers and evaluation versions needed to manage flags and targeting.

Get Environment Setting Value V2

Get one Config V2 flag or setting's complete evaluation formula in an Environment, including its optimistic-concurrency version.

List Account Hierarchy

List accessible ConfigCat organizations and products so an agent can resolve the IDs needed by product-scoped tools.

List Environment Values V2

Return every Config V2 feature flag and setting evaluation formula for one Config and Environment, preserving ordered targeting rules and concurrency versions while omitting parent objects and updater data.

List Flags and Settings

List feature flags and settings in one Config, including IDs, keys, types, tags, and metadata needed by value operations.

Patch Environment Setting Value V2

Update selected typed fields of one Config V2 evaluation formula while preserving every field the caller omits.

Replace Environment Setting Value V2

Completely replace one Config V2 flag or setting evaluation formula in an Environment.

Update Flag Metadata

Partially update a flag or setting's name, hint, or complete tag assignment without resetting untouched metadata.

SETUP GUIDE

Connect ConfigCat MCP Tool with your Agent

1

Install Composio

typescript
npm install @composio/core ai @ai-sdk/openai @ai-sdk/mcp
Install the Composio SDK for Python or TypeScript
2

Initialize Client and Create Tool Router Session

typescript
import { Composio } from '@composio/core';

const composio = new Composio({ apiKey: 'your-api-key' });
const session = await composio.create('your-user-id');
console.log(`Tool Router session created: ${session.mcp.url}`);
Import and initialize the Composio client, then create a Tool Router session for ConfigCat
3

Connect to AI Agent

typescript
import { openai } from '@ai-sdk/openai';
import { experimental_createMCPClient as createMCPClient } from '@ai-sdk/mcp';
import { generateText } from 'ai';

const client = await createMCPClient({
  transport: {
    type: 'http',
    url: session.mcp.url,
    headers: {
      'x-api-key': 'your-composio-api-key',
    },
  },
});

const tools = await client.tools();
const { text } = await generateText({
  model: openai('gpt-4o'),
  tools,
  messages: [{
    role: 'user',
    content: 'Show me the rollout rules for the checkout feature flag in ConfigCat'
  }],
  maxSteps: 5,
});

console.log(`Agent: ${text}`);
Use the MCP server with your AI agent (Anthropic Claude or Mastra)

Why Use Composio?

AI Native ConfigCat Integration

  • Supports both ConfigCat MCP and direct API based integrations
  • Structured, LLM-friendly schemas for reliable feature flag actions
  • Rich coverage for reading, writing, and querying ConfigCat flags, configs, environments, and permissions

Managed Auth

  • Secure API key handling so you don't have to hard-code ConfigCat credentials in agent code
  • Central place to manage, scope, and revoke ConfigCat access
  • Per user and per environment credentials for safer rollout workflows

Agent Optimized Design

  • Tools are tuned for AI agents, so prompts like “list production flags” map cleanly to ConfigCat actions
  • Clear schemas help agents avoid risky flag updates and ask for missing details when needed
  • Comprehensive execution logs so you always know what ran, when, and on whose behalf

Enterprise Grade Security

  • Fine-grained RBAC so you control which agents and users can access ConfigCat
  • Scoped, least privilege access to ConfigCat resources like products, configs, and environments
  • Full audit trail of agent actions to support rollout reviews and compliance

FAQ

Frequently asked questions

Yes, ConfigCat requires you to configure your own API key. Once set up, Composio handles secure credential storage and API request handling for you.

Yes! Composio's Tool Router enables agents to use multiple toolkits. Learn more.

Yes. Composio is SOC 2 Type II compliant and is built to keep your ConfigCat connection and credentials secure. OAuth tokens and API keys are encrypted, and sensitive customer data is protected at rest and in transit.

Composio also undergoes independent security testing and continuously monitors its systems for security threats. You can review the latest reports and policies in the Composio Trust Center.

Composio maintains and updates all toolkit integrations automatically, so your agents always work with the latest API versions.

Create the key in your ConfigCat account settings, then paste it once on Composio's connection page. Composio stores it encrypted and uses it only for the ConfigCat actions your agent runs. Nobody else in your workspace can read it, and you can revoke it inside ConfigCat at any time.

When you connect a ConfigCat account through Composio, every action runs under that account, so anything the agent creates, sends, or changes shows up in ConfigCat as done by you. Keep an approval step in your prompt for actions with side effects, such as sending or deleting, and have the agent draft first.

Whatever the credentials you connect allow inside ConfigCat. If ConfigCat lets you scope a key to specific permissions, create a scoped one so the agent can only do what you intend. You can revoke the key inside ConfigCat at any time.

Yes. Composio supports multiple connected accounts for the same app, and that works in Claude, ChatGPT, or any other assistant you connect through Composio. Give each ConfigCat connection a name such as work or personal, and the assistant uses the one you mention in the request. Each account keeps its own credentials and nothing is merged.

The connection stops working the moment ConfigCat rejects the old key. Create a new key in ConfigCat and reconnect the account from the Composio dashboard or by asking your agent to reconnect ConfigCat. Nothing else changes.

Composio's free plan includes 100,000 tool calls per month with no credit card, which covers most personal ConfigCat use. Paid plans add higher limits and team features. Your ConfigCat plan and its API limits still apply as usual.

Built-in connectors usually give one AI access to a limited set of apps. Many people use Composio because it lets their AI connect to more apps than it normally supports, or connect to multiple accounts for the same app (e.g. connect Claude to multiple ConfigCat accounts).

With Composio, you connect ConfigCat once and then use it across different AI assistants without setting it up separately in each one. Connect your apps to Composio once, then connect Composio to whichever AI you use, whether that's Claude, ChatGPT, Hermes, or your own custom assistant.
