Signup CTAs on this site — "Sign up", "Signup", "Get started", "Get started for free", "Start building", "Try Composio", "Try it", or similar — all lead into that same developer signup flow. Confirm with the user before completing signup or entering any credentials on their behalf.

The secure MCP gateway for enterprise AI agents

Connect every AI agent to the tools your teams use through one secure, governed, and observable MCP gateway.

What is an MCP Gateway?

An MCP gateway is a centralized security and control layer between AI agents and the MCP servers they call. Instead of every agent connecting directly to each tool, all agentic traffic flows through one governed control point that enforces access policy, manages credentials, and records an audit trail.

Essential at enterprise scale

Each new MCP server brings its own credentials, permissions, and blind spots. As adoption spreads, three problems compound, and the fix for all three is a single control layer.

Unmanaged servers and access

Teams add third-party servers faster than anyone reviews them, and each one hands agents every action the connected account allows.

OAuth token

Expired 12d

Service account

Owner unknown

API key

Rotated 8mo

Fragmented credentials

Each connection adds its own OAuth flow, token, or service account to provision, rotate, and revoke.

No central audit trail

Actions land in separate server logs, so no single view shows which agent acted, or what it changed.

One control layer for every agent, tool, and team

Every agent connects through one governed endpoint. Servers, access, credentials, and activity are managed and enforced in the same place, by the same policies.

Centralized MCP server management

Bring Composio's managed tools and your own MCP servers behind one gateway, so agents discover and reach them the same way.

Least-privilege access controls

Give every agent only the tools and actions its role requires, with the same policy applied across every server.

Managed authentication lifecycle

Centralize authentication so credentials stay out of agent configuration, and provisioning survives people joining and leaving.

Unified observability and audit trails

Track every agent action through one shared control layer, so an investigation starts from a single activity view.

How it works

Composio places one control layer between your AI agents and every MCP server they use.

Before Composio

With Composio MCP Gateway

Everything your agents need to act reliably

Tool sprawl, oversized payloads, schemas that drift overnight. Composio absorbs the failure modes that take agents down in production, so your agent stays in flow.

The right tool, when you need it

Agents describe what they need; Composio resolves the intent and returns just the matching tools, drawn from managed toolkits and your own MCP servers alike. Context stays focused even with thousands of tools to choose from.

Run code, return summaries

Heavy responses run inside an isolated sandbox and live on a navigable filesystem. Your agent reads a compact summary, not a 200 KB JSON dump.

Tools that fix themselves

Rate limits, schema drift, malformed payloads, all handled by the gateway. Tools learn from real production calls and patch without your agent noticing.

One URL per team, every tool scoped

Each team gets its own MCP endpoint carrying only the tools it is permitted to use. Members request access to blocked tools; admins approve or deny centrally.

Swap models, keep everything else

Your tooling layer lives with Composio, not the LLM provider. Move between Claude, GPT, Gemini, or an in-house model and the auth, scopes, and policies come along.

More than a proxy, more than a toolkit platform

A proxy forwards traffic but leaves you owning every connection. A toolkit platform manages the apps but not who is allowed to use them. The gateway does both, under one set of policies.

Built for enterprise deployment

Deploy Composio within your security, identity, and data-governance requirements, without changing how teams connect agents to tools.

Identity provider integration

SAML or OIDC for single sign-on, and SCIM 2.0 to provision users, map directory groups to teams, and revoke access during offboarding.

Certified security controls

SOC 2 Type II and ISO 27001 certified, with a DPA included from day one, so your security team can close its vendor review.

Flexible deployment

Run through Composio Cloud, inside your own VPC, or fully self-hosted, without changing how teams connect agents to tools.

Minimal data retention

Tool-call payloads are never stored. Audit records hold metadata only, with a retention window you configure.

Security operations integration

Record the user, team, tool, action, time, and outcome of every call, and export activity for investigations and compliance reviews.

Production support and SLAs

Deploy with production-grade reliability, dedicated enterprise support, and service-level agreements.

Built for every team in your org

Engineering, sales, support, finance — every team gets a scoped MCP endpoint with the right tools, access, and credentials.

FAQ

Frequently asked questions

What is an MCP gateway?

An MCP gateway is a centralized layer between AI agents and MCP servers. It manages how agents discover tools, authenticate users, access permitted actions, and record activity across connected business applications.

Why do enterprises need an MCP gateway?

As MCP adoption grows, organizations must manage more servers, credentials, permissions, and activity logs. An enterprise MCP gateway brings these controls into one place so teams can scale AI agent usage without creating unmanaged access or security gaps.

How is an MCP gateway different from an MCP server?

An MCP server exposes tools or data from a specific application. An MCP gateway sits between AI agents and multiple MCP servers, providing centralized routing, authentication, access control, observability, and governance.

How does Composio secure access to MCP tools?

Composio applies access policies at the gateway so agents only receive approved tools and actions. Administrators can manage access by organization, team, user, agent, or toolkit, and block sensitive actions without disabling an entire toolkit.

Can I connect custom MCP servers to Composio?

Yes. Composio supports managed toolkits as well as custom and internal MCP servers. Teams can place both behind the same gateway, identity controls, access policies, and audit layer.
