New access paths
MCP can connect AI agents to tools and enterprise systems through a common protocol.
MCP security
Build MCP security on trustworthy evidence.
Security starts by separating what is configured from what is running or independently verified. Policy should follow evidence, not assumptions.
Direct definition
What is MCP security?
MCP security is the practice of identifying and managing clients, declared servers, tools, capabilities, and verified connections created through the Model Context Protocol.
AxLoop knowledge base
The visibility problem
Evidence must come before control.
Unclear ownership
Clients and servers may be configured by different users and teams.
False certainty
A declaration or process name alone does not prove an active or authorized MCP interaction.
How AxLoop helps today
Discover from the endpoint outward.
AxLoop identifies supported AI applications, agents, local models, runtimes, and MCP configuration evidence. Each finding keeps installed, configured, running, and independently verified states distinct.
- Identify supported software and configuration evidence
- Preserve device and user scope
- Monitor meaningful state changes
Questions teams ask
- Q1Which MCP servers are configured?
- Q2What capability categories are recognized?
- Q3What evidence would verify an active interaction?
Common questions
Answers, briefly.
- What are the main MCP security risks?
- Common risks include over-permissioned tools, servers from untrusted sources, credentials stored in local configuration, tool descriptions that enable prompt injection, and unexpected paths to sensitive data or production systems.
- Is an MCP gateway enough for MCP security?
- Gateways help govern traffic that passes through them. Locally configured servers can bypass a gateway entirely. Endpoint discovery complements a gateway by showing which MCP connections exist outside it.
- How should teams prioritize MCP findings?
- Start with servers exposing write, execute, or broad data-access capabilities, servers without a known owner, and connections to sensitive systems. Capability classification helps rank findings without inspecting payloads.
- Can MCP security work without reading tool-call content?
- Yes. Server identity, transport, supported capability classifications, device context, and evidence state can support review without reading prompts or parameters. Runtime tool-call and policy evidence belong to the product direction.
