TapPass

Ways to connect

There’s no single way to adopt TapPass. Pick the shape that fits how your agents already run — you can mix them, and every path produces the same governed, audited decisions.

The four surfaces

Section titled “The four surfaces”
Surface Shape You change Best when
Gateway TapPass in the request path, OpenAI-/Anthropic-compatible One line — your base_url You want model traffic governed and provider keys handled, with zero code change
Verdict API TapPass beside your app; you execute One call at each decision point You keep execution in your own runtime, incl. non-LLM actions
Hooks The verdict API from a hook you already have A few lines in a pre-execution hook Your agent/IDE/gateway has a pre-tool or pre-call seam (Claude Code, Cursor, LiteLLM)
Governed MCP A governed MCP endpoint Point your MCP client at it Your agent speaks MCP and you want every tool call brokered

How to choose

Section titled “How to choose”
  • Want the least work and you’re calling an LLM? Swap your base URL for the gateway. Your agent never holds a provider key, streaming and audit come for free, and a block comes back as a readable message instead of an error.
  • Governing things that aren’t model calls — tool calls, database writes, state transitions — or you don’t want a proxy in the path? Use the verdict API: ask, then act on allow / block / needs_approval.
  • Already have a hook point (Claude Code PreToolUse, a LiteLLM guardrail, your framework’s tool wrapper)? Drop the verdict call into that hook — ambient governance, no rewrite.
  • Your agent speaks MCP? Point it at the governed MCP endpoint and every tools/call is governed without touching agent code.

What’s the same everywhere

Section titled “What’s the same everywhere”

Whichever surface you use, you authenticate with a tp_ key, the decision is made server-side against the agent’s policy, obligations (like redaction) are applied, and the outcome is written to a tamper-evident audit trail. An allow carries a short-lived signed mandate your downstream can verify offline.
