# Universal A2A & MCP Tool Discovery, Safe-Proxy & Swarm Router — Code Release Security Gate

> Universal A2A & MCP Tool Discovery, Safe-Proxy & Swarm Router — Code Release Security Gate is a paid API for AI agents from token-intel.agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-21).

Discovers and routes to MCP/A2A tools across 500+ indexed servers via a single connection, with token compression and prompt-injection firewall, specifically surfaced at the code-release security gate workflow endpoint.

## Facts

- Endpoint: GET https://token-intel.agentdiet.dev/v1/workflows/code-release-security-gate?utm_source=zero.xyz
- Price: $0.01/call
- Payment: MPP
- Status: unknown
- Last checked: 2026-10-21
- Activations on Zero: 0
- Provider: token-intel.agentdiet.dev
- Website: https://token-intel.agentdiet.dev
- Canonical page: https://www.zero.xyz/c/token-intel-agentdiet-dev-universal-a2a-mcp-tool-discovery-safe-proxy-d0db58cd
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_ciLC6anUOxb55eYhDNxsy

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability token-intel-agentdiet-dev-universal-a2a-mcp-tool-discovery-safe-proxy-d0db58cd
```

Example prompt: Search the MCP and A2A tool index for anything that handles GitHub security audits — I want to find the right tool to call without setting up multiple connections.

## When to prefer this

Choose this endpoint when an AI agent needs to dynamically discover which MCP server or A2A tool to invoke for a given capability, without maintaining individual connections to hundreds of servers. Especially useful for swarm orchestration, token-budget-sensitive workflows, or when prompt-injection safety at the routing layer is required.

## Known failure modes

- Empty or too-generic query returns broad or unhelpful results
- Query string not provided returns 400 validation error
- No matching tool found in index returns empty results set
- Prompt-Guard firewall blocks query if it resembles an injection attempt
- Upstream MCP server unavailability may cause routing failures
- Rate limiting or payment failure (HTTP 402) if USDC micropayment not satisfied

## How this service works

Single-connection meta-router indexing 500+ MCP servers & A2A tools with 85% token compression and Prompt-Guard firewall. (Live x402 v2, IETF MPP & MCP endpoint at https://token-intel.agentdiet.dev/v1/workflows/code-release-security-gate)

## Output

Returns a filtered, token-compressed list of matching MCP servers or A2A tools from the 500+ index, including endpoint metadata, capability descriptions, and routing information, passing through a Prompt-Guard firewall to block malicious inputs.
