Prevent · MCP Server

Security context, built into code generation.

A coding agent knows generic security advice. Heeler adds what it cannot know: your policies, where the code runs, what it connects to, and what is already open.

What Heeler MCP gives your agent

Full security context for the agent, without the manual work.

Heeler brings your code, deployments, policy and dependencies into the agent.

Why not just let the agent handle it?

A coding agent can write the code. It does not know your rules or where the code will run.

Security has to be part of the generation, not a scan afterwards.

What it costs without Heeler

Every step gets more expensive, and the cost compounds.

Paid in developer time, tokens, retries and rework.

Developer time

Without HeelerHunting for context, every task

With HeelerThe agent asks Heeler

Tokens in the context window

Without HeelerDocs and scan output crowd out the code

With HeelerJust the answer: verdict, count, fix version

Agent reasoning

Without HeelerGuesses your rules, gets some wrong, retries

With HeelerFacts, so fewer turns

Fixes that come late

Without HeelerFixed late: at review, or in production

With HeelerCaught while the code is written

Built-in security reviews

Security reviews any developer can run from the agent.

Four ready-made reviews, one pick from the agent's prompt menu.

New endpoint check

Same auth as your other routes

secure_development_checklist

Risk review of the change

Access, injection, SSRF, data exposure

secure_code_risk_review

Code findings on touched files

High and critical fixed first

heeler_sast_pass

Dependency check before merge

Urgent findings, safe upgrades

Reporting

Board-ready security reports, built by the agent.

The agent pulls the numbers from Heeler and builds the report in your branding.

Day to day

What needs attention now

Overdue work by team and owner, and blocked PRs.

Trends

Whether it is getting better

Findings opened vs closed, guardrail pass rates.

Peers and leadership

Reports in your brand

One-page reports for the CISO and board. CSV for audits.

Safe to connect

Give every agent context without giving it control.

Connecting an agent does not widen anyone's access.

Read-only by default

Agents read findings and context, never change them.

Your permissions, no more

Each developer sees only what they already can in Heeler.

Changes need an admin

SLO overrides and scheduled fixes only, by an admin, audited.

Works where your developers work

Every agent on the team gets the same security context.

Any agent, the same Heeler context. Setup is one line and a sign-in.
