MCP Governance

Every tool call. Checked.

Point your agents at one endpoint and govern every tool call to any MCP server. Each call is checked against your rules before it runs.

How your setup works

One endpoint in front of every tool.

Your agents already speak MCP. Point them at Trinitite instead of each tool server, and we forward every call to the right place — GitHub, Postgres, Slack, or any MCP server you register.

On the way through, every call is checked against your rules and passed, corrected, masked, or blocked — with a signed record of what happened.

One endpoint

any MCP server · any tool

Pin a high-risk tool to a specific Guardian and policy. A silent config change gets blocked, not quietly honored.

How It Works

Three Steps. Every Tool Call.

Agent calls a tool

Your AI agent requests a tool action through MCP — read a file, query a database, call an API.

Proxy checks policy

The call passes through Trinitite's proxy. Your rules are checked before the tool runs.

Allow, rewrite, or block

Safe calls pass. Risky calls get rewritten. Dangerous calls are stopped before they execute.

Every Call Logged

Full forensic record of every tool call, every argument, every verdict. Searchable by agent, tool, time, or outcome. Auditor-ready from day one.

Automatic Correction

When a tool call breaks a rule, parameters get rewritten so the call still works — safely. No failed requests. No downtime.

Validate Before You Deploy

Test every policy change before it goes live.

Describe a risk in plain English. The Scenario Factory generates up to 100 test cases. Run them against any policy version. When a real incident happens, turn it into a permanent regression test with one click. Policy changes never reach production without proof they work.

This is CI/CD for governance — a test harness your compliance team can run before every policy update.

Full Audit Trail

From draft to production, every change tracked.

Policies go through a structured workflow: Create, Ingest, Edit, Finalize, Activate. Every change is attributed — who changed what, when, and why. Roll back in one click. Auditors get a complete chain of custody for every governance rule.

When a regulator asks “who authorized this policy?” — the answer is one search away.

Capabilities

Complete Tool Governance

Transparent Proxy

Deploys between your agents and MCP servers with zero code changes. Point your agents at Trinitite instead of directly. Everything else stays the same.

Allow/Block Lists

Choose which tools each agent can use. Block file_delete for junior agents. Allow database_read but block database_write. Your rules, per tool.

Argument Constraints

Limit what tools can access. A tool can read /tmp but not /etc. A query can access the users table but not the payments table.

Sequence Detection

Enterprise

Catch attack patterns that span multiple calls. If an agent reads credentials then calls an external API, the sequence is blocked.

Guardian AI Routing

Pro

Send high-risk tool calls through a Guardian for deeper analysis. Simple calls pass through. Complex ones get a second opinion.

Session Replay

Enterprise

See every tool call in order, with full context. Who called what, when, with what inputs, and what happened next.

Automatic Correction

When a tool call breaks a rule, Trinitite rewrites the parameters so the call still works — safely. No failed requests. No downtime.

Full Audit Trail

Every call, every verdict, every correction is logged. Search by agent, by tool, by time, or by outcome. Always ready for auditors.

Use Cases

What Customers Protect

Data Exfiltration Prevention

Block agents from sending sensitive data to external APIs. Detect read-then-send patterns before data leaves your perimeter.

Least Privilege Enforcement

Give each agent access only to the tools and data it needs. No more over-permissioned service accounts.

Compliance Logging

Every tool interaction is logged with full context. Meet SOC 2, HIPAA, and ISO 27001 audit requirements out of the box.

Activity Dashboard

Full visibility into every agent tool interaction.

Full visibility into what your agents are doing with external tools. Every tool call governed, every block rate tracked. The 7-day activity overview shows you exactly where your governance layer is working — and where it's catching threats.

When leadership asks “how many tool calls did our agents make last week, and how many were blocked?” — you have the answer in seconds, not days. Metrics that turn governance from a cost center into a measurable security function.

Server & Tool Discovery

Know your entire agent tooling surface.

Every connected MCP server, every tool it exposes, every governance badge applied. Discover your full agent tooling surface in one catalog. When a new server connects, you see it immediately — with its full capability manifest and governance status.

Shadow tooling is the new shadow IT. Agents connecting to unvetted MCP servers represent ungoverned risk. The server catalog makes every connection visible, every tool discoverable, and every gap in governance coverage obvious.

OAuth Consent Governance

Agent access requests, governed by policy.

Agents requesting access to external systems go through consent governance. Scopes evaluated against policy. Over-privileged requests denied automatically. Every OAuth token grant is checked, logged, and attributed to the requesting agent and its purpose.

When an agent requests admin:write scope but only needs read access, the consent governance layer catches it before the token is issued. No human in the loop needed for clear policy violations — but full escalation paths when the decision is ambiguous.

Infrastructure Health

Know your governance layer is working before agents need it.

Connection pools, SSE streams, batch processing — infrastructure health for your governance layer. Know it's working before your agents need it. Continuous monitoring of every proxy component ensures zero-downtime governance enforcement.

Governance infrastructure that goes down silently is worse than no governance at all — because you think you're protected when you're not. Health monitoring catches degradation before it becomes an outage, with alerts that reach the right team before agents start failing.

Argument Constraints

Define exactly what's permissible for every tool call.

Define exactly what arguments are permissible for each tool call. Restrict email recipients to company domains. Block DELETE queries. Route high-risk calls through Guardian AI. Argument-level governance is where broad policy becomes precise, enforceable control.

Allowing a tool is only half the equation. An agent with database_query access that can run DROP TABLE is a liability. The argument builder lets you construct fine-grained rules that constrain not just which tools are available, but exactly how they can be used.

Configuration AuditEnterprise

Every configuration change, attributed and logged.

Every change to every MCP configuration is logged with attribution. Who changed what server, what policy, what OAuth client — and when. The configuration audit stream gives you a complete record of every governance decision, not just every agent action.

When an auditor asks “who authorized this MCP server connection?” or “when was this policy last modified?” — the answer is one search away. Full diff-level visibility into configuration changes, with tamper-proof logging that satisfies SOC 2 and ISO 27001 evidence requirements.

The Vocabulary

What is MCP governance?

MCP governance is the control layer between your AI agents and the Model Context Protocol tools they call. Trinitite deploys as a transparent proxy: every tool call is checked against your policy and allowed, rewritten, or blocked before it runs — and each decision writes a signed receipt you can replay later, not just read.

MCP tool governance

Choose which tools each agent may call, then constrain how. Allow/block lists with pattern matching set the surface; argument constraints cap input length and forbid dangerous payloads; result filtering redacts sensitive fields and validates every result against its declared schema. High-risk tools can be pinned to a specific guardian, policy hash, and OAuth scope — a silent config change is blocked, not quietly honored.

MCP server governance

Register every upstream MCP server once; Trinitite merges their catalogs into a single namespaced list your agents see as one endpoint. Policy runs on resource reads and prompt fetches too — and on server-initiated messages, so a malicious tool server can't use the back-channel to drive your client. Shadow tooling becomes visible the moment a new server connects.

MCP token governance

Short-lived, just-in-time non-human identity tokens are the native auth for the gateway — scope-locked and audience-pinned (RFC 8707), so a token issued for one tool server can't be replayed against another. Every session is pinned to the identity that created it, and OAuth delegation refuses to mint codes for upstreams the user never consented to: the confused-deputy attack closed by construction.

MCP security governance

Deterministic blocklists only catch known-bad calls — and an agent's reasoning is exactly what prompt injection hijacks. The Agent Action Guard is an independent, embedding-based gate that scores the semantics of the action itself, so a hijacked agent still can't make “delete the production database” look safe. It survives prompt injection because it never trusts the model's explanation, and every verdict is anchored to the exact policy clause it enforced.

MCP governance framework

Compose three pipelines: a fast deterministic rules engine, an SLM guardian, and a chained mode that runs rules first and falls through to the SLM only on ambiguous verdicts. In deterministic mode every verdict carries a receipt — model digest, adapter pin, seed, input/output digests — so an auditor can reproduce the decision bit-for-bit. Looking for the broader pattern across shells and skills? See tool governance, of which MCP governance is the canonical implementation. The same brain governs the AI your people use outside your agents — browser ChatGPT, Claude, Gemini — through universal AI governance.
