Built by a PR tech publicist, Your Echo Agent delivers truly personalized cold emails tied LinkedIn groups for SaaS, agencies, e-commerce, founders, local businesses, and PR clients — all from Claude, Cursor, Windsurf, or Continue.

Short Description (概要): An MCP server providing FEP (Free Energy Principle) matrix-pruning tools (resolve_fep_consensus) for multi-agent deadlock resolution and syntax-locked A2A consensus.

An MCP bridge that exposes A2A agents as tools in VS Code agent chat, enabling natural language delegation to remote agents with multi-turn conversation and configurable authentication.

Enables AI agents to check trustworthiness before recommending URLs, products, or organizations, with fail-closed pass/fail verdicts and attested-only recommendations.

Enables MCP clients to interact with A2A agents through four ordinary tools, translating agent discovery, messaging, task reading, and cancellation between the A2A and MCP protocols, with support for the tasks extension.

Enables trust, reputation, and economic accountability for MCP by proxying between clients and servers, enriching every tool invocation with trust evaluation, KYA tiers, spending limits, and delegation chains.

Enables Claude to connect and interact with A2A Protocol agents, allowing discovery of agent capabilities, sending messages to remote agents, managing multi-turn conversations, and viewing artifacts returned by agents.

A2A Governance Bridge - MCP server providing AI-powered tools and automation by MEOK AI Labs

Enables AI agents to store, read, extend, and share encrypted persistent memory, with pay-per-use access via x402 payments on Base.

Paid remote MCP gate for caller identity, agent scope, task intent, data class, policy verdicts, and audit receipts.

Enables enterprise MCP clients and partner agents to execute tenant-isolated underwriting, claims, and compliance workflows with durable step checkpointing, evidence-grounded tool calls, and deterministic PDF citation receipts. It supports A2A task dispatch and MCP JSON-RPC operations while blocking cross-tenant access and ungrounded deliverables.

Enables Claude Code to delegate coding work to a team of Google Antigravity specialists, dispatching tasks to particular roles, listing available agents, checking or cancelling task status, and validating delivered work against acceptance criteria and verification commands. It keeps the leader model in control by returning short results with token usage, git change summaries and output tails instead of the full work.

Enables agents to discover and transact grocery retail-media opportunities across 20 markets, including resolving jurisdiction and actors, finding makers and banners, checking eligibility, retrieving signed banner cards, quoting packages, submitting demands, handoffs, measurement, renewals, and audit logging through MCP tools.
