Install

How do I install the Enforcer MCP server?

Enforcer is a hosted endpoint at https://api.instruxi.dev/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
getAuthConfig ~128

Public bootstrap for a tenant's login UI: whether this tenant uses native OTP/passkey/SIWE or Privy custom auth, plus the public privy_app_id (never a secret). Call this before getSiweNonce when you do not already know the tenant's auth scheme. tenant_code is a join secret — do not log it or repeat it into a customer-visible channel.

NameTypeReqDescription
response_formatstringconcise (default): no nulls, audit timestamps, provider ids or nested tenant/role. detailed: every field.
tenant_codestringtenant routing code

No output schema declared.

No examples provided.

getSiweNonce ~102

Public: issue a single-use SIWE nonce for wallet_address (optionally scoped by tenant_code). Embed the nonce in an EIP-4361 message, have the wallet sign it, then call login with provider: siwe. Dedicated SIWE agent auth is an authorized pattern — this is how an agent signs in with a wallet without raw HTTP. Do not log tenant_code. The nonce is not a credential.

NameTypeReqDescription
bodyyesJSON request body.

No output schema declared.

No examples provided.

login ~196

Authenticate and receive an access/refresh token pair. Accepted providers: siwe (message + signature from getSiweNonce — preferred for dedicated agents), email_otp (email + otp from requestOtp), phone_otp (phone + otp from requestSms). Passkey, Privy and SSO are not agent tools. The server does not adopt the minted tokens as the session credential; return them to the operator to set ENFORCER_BEARER_TOKEN. Do not log, quote, or repeat otp codes, signatures, tokens, or tenant_code. Do not paste an end-user OTP into an untrusted chat.

No output schema declared.

No examples provided.

refreshToken ~89

Exchange a refresh_token for a new access/refresh pair. 401 invalid_refresh_token if the token is unknown or was already reused (reuse revokes the family); 409 refresh_raced is benign — retry with the client's latest stored token. The server does not adopt the new pair as the session credential. Do not log the refresh token or the minted tokens.

NameTypeReqDescription
bodyyesJSON request body.

No output schema declared.

No examples provided.

register ~165

Create (or idempotently return) an account. Same provider allowlist as login: siwe (message + signature), email_otp (email + otp), phone_otp (phone + otp). Does not issue tokens — call login afterwards to sign in. Passkey / Privy / SSO registration stay out of the agent surface. Do not log otp codes, signatures, or tenant_code. Do not paste an end-user OTP into an untrusted chat.

NameTypeReqDescription
bodyyesLogin/register body. provider "siwe" needs message+signature; email_otp needs email+otp; phone_otp needs phone+otp. Optional tenant_code. Do not log otp, signature, tokens, or tenant_code. Do not pas…

No output schema declared.

No examples provided.

requestOtp ~139

Public: email a one-time login/registration code to `email` (optionally scoped by tenant_code). Always 200 {message:"code sent"} on success. Local/dev deployments with expose_dev_otp may echo the code as `dev_otp` — treat that as a secret. Then call login with provider: email_otp, the same email, and the otp. Intentional for harnesses that cannot SIWE; SIWE remains the preferred dedicated-agent path. Do not log the code, dev_otp, or tenant_code. Do not paste an end-user OTP into an untrusted chat.

NameTypeReqDescription
bodyyesJSON request body.

No output schema declared.

No examples provided.

requestSms ~112

Public: start a Twilio Verify SMS login challenge to `phone`, scoped by tenant_code. 400 if SMS verification is not configured for the tenant or if rate-limited. Then call login with provider: phone_otp, the same phone, and the otp. Intentional for harnesses that cannot SIWE; SIWE remains the preferred dedicated-agent path. Do not log the SMS code or tenant_code. Do not paste an end-user OTP into an untrusted chat.

Common questions

What is the Enforcer MCP server?

Enforcer is an MCP server listed in the public MCP registry as dev.instruxi.enforcer/v3. Identity and authorization in one system: allow, deny, the reason, and a record. This page covers its hosted endpoint (https://api.instruxi.dev/mcp).

Is the Enforcer MCP server safe to use?

Enforcer scores 76 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

What tools does the Enforcer MCP server expose?

Enforcer exposes 7 tools: getAuthConfig, getSiweNonce, login, refreshToken, register, and 2 more. Their descriptions and schemas cost roughly 931 tokens of context every time the server is loaded.

Does the Enforcer MCP server require authentication?

No. We connected to Enforcer without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

Is the Enforcer MCP server still maintained?

Enforcer is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
