// INTEGRATION

Use Intercept with OpenAI Codex

Add policy enforcement to Codex in one line.

Config file: ~/.codex/config.toml (global) or .codex/config.toml (project)

Codex uses TOML format, not JSON. Each server is a [mcp_servers.name] table.

// BEFORE

A standard MCP server in your Codex config -- no controls.

config.toml

[mcp_servers.stripe]
command = "npx"
args = ["-y", "@stripe/mcp-server"]

[mcp_servers.stripe.env]
STRIPE_SECRET_KEY = "sk_live_..."

// WITH INTERCEPT

Wrap the server command with Intercept. Same config structure, policy enforced.

config.toml

[mcp_servers.stripe]
command = "npx"
args = ["-y", "@policylayer/intercept", "-c", "policy.yaml", "--", "npx", "-y", "@stripe/mcp-server"]

[mcp_servers.stripe.env]
STRIPE_SECRET_KEY = "sk_live_..."

// WHAT YOU GET

Rate limits

Cap tool calls per minute, hour, or day

Access controls

Allow, deny, or conditionally gate any tool

Spend caps

Limit financial operations with daily thresholds

Audit logs
