MCP security audit for your server and tools.

We review tool authorization, authentication, schemas and the client-server trust boundary before your next release. Share your server scope and target date to discuss the review.

Scope

What’s in the audit.

Server hardening
Schema design
Trust model
Why this exists

MCP gives a model your tools. Treat that seriously.

Every tool you expose through MCP is a privilege you’ve granted to a model that can be manipulated by anyone with text in its context window. Tool descriptions are attack surface. Schemas are attack surface. The trust between client and server is attack surface. The audit covers all of it.

FAQ

Questions.

A code-level and design-level review of your Model Context Protocol server. We audit the transport, the tool surface, the schemas, the auth model, and the trust assumptions between the server and any connecting client.

Yes, on request. Client-side audits cover how the agent decides which MCP server to trust, how it handles tool descriptions, and how it constrains what tools the model can invoke.

Yes — we publish on the discipline regularly. See the research below for examples including a design flaw analysis in the Anthropic MCP SDK and the broader MCP breach index.

Yes. The MCP ecosystem distributes tools as packages; we review dependency trust, signing, and the supply-chain integrity of anything your server pulls in.

Standard scope. We cover the HTTPS transport, auth tokens, session handling, and rate-limit behavior. The audit also tags chain-of-custody assumptions explicitly.

Two to four weeks for typical scope. We scope and quote against your specific server before you commit.
