TAP

Tool Authorization Protocol (TAP)

Credential isolation, approval gating, and connector routing for AI agents.

This repository contains the code that is most useful for:

• auditing request routing and connector behavior
• debugging failed requests
• understanding approval flows
• improving connector-side request shaping
• contributing fixes to the core TAP experience

[!WARNING] Self-hosting means you own the security of your credentials and signing keys. TAP keeps secrets out of your agents, but running it yourself puts the host hardening, key isolation, and correct policy-engine operation on you. It's a path for teams that are well versed in security. For everyone else the hosted version is strongly recommended: credentials sit in a hardware enclave we can't read into, with no ops to run. Start free at tap.human.tech.

Start Here

• crates/tap-proxy/src/routing.rs — how TAP resolves connector target shapes
• crates/tap-proxy/src/placeholder.rs — credential substitution and position validation
• crates/tap-proxy/src/policy.rs — approval policy enforcement
• docs/ — full documentation including self-hosting guide

Included

• core proxy and storage crates
• Telegram and Matrix approval bots
• remote MCP server (tap-mcp)
• CLI
• docs (self-hosting, API reference, credential setup)

Not Included

• enclave deployment glue (CCE policy generation, release-policy automation, ARM templates, env config)
• production workflows and secret bootstrapping
• managed hosting operations glue
• the hosted dashboard UI source (a placeholder is shipped so the proxy compiles)

The enclave key-management source is included (key_provider_enclave.rs, kms_azure.rs, skr.rs) — it's the custody model documented at docs.tap.human.tech/security, and each hosted release's enclave measurement is published in measurements/. Hosted deployment and operational infrastructure are maintained separately from this repository.

Testing

# Needs Postgres (default postgres://tap:tap@localhost:5434/tap, override with
# POSTGRES_DATABASE_URL). Isolated suites parallelize; env-mutating unit tests stay serial.
