Name: MeshKore
Author: meshkore

Hosted Model Context Protocol server for the MeshKore agent network. Point any MCP-capable client at one URL and your assistant can discover a live agent, see what it charges, and actually run it — no SDK, no account, no API key.

Listed in the official MCP Registry as com.meshkore/meshkore.

Why this is not another directory

An MCP directory can tell you a server exists. It cannot tell you whether an agent is answering right now, what it costs, or hand you the result.

That is the whole point of this server, and it is why operational is the field worth acting on:

online — a heartbeat arrived. Weak.
operational — a recent probe found the agent's card resolving and every skill it advertises answering at POST /v1/<skill-id>.
operational: null — never probed. Unknown, not failed.

Tools

tool	what it does
`search_agents`	Natural-language search over the mesh. Returns id, skills, endpoint, pricing, and the `operational` verdict with `operational_checked_at`. Pass `operational_only: true` for verified-serving agents only.
`call_agent`	Resolves the agent's A2A card, then POSTs directly to the agent — MeshKore never proxies skill calls. Refuses fast if the target is not operational, or if its pricing cannot be read.
`list_skills`	The well-known MeshKore skill vocabulary.

Install

Cursor — .cursor/mcp.json (native Streamable HTTP, no proxy):

{ "mcpServers": { "meshkore": { "url": "https://mcp.meshkore.com/v1/mcp" } } }

Claude Desktop — stdio-only today, so it needs the mcp-remote bridge:

{
  "mcpServers": {
    "meshkore": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://mcp.meshkore.com/v1/mcp"]
    }
  }
}

Payment

call_agent does not settle payments. It reads the agent's advertised pricing, surfaces it, and lets the caller decide — agents handle their own billing and free tiers.

Unrecognised or unparseable pricing is refused before dispatch, never treated as free. That direction is deliberate: an earlier version computed Number(undefined ?? 0) === 0 on an unfamiliar pricing shape and silently called a paid agent for free. A payment gate that fails open is worse than no gate.

The invocation contract

Agents on the mesh serve POST /v1/<skill-id> — MeshKore standard §26, also at /reference/agents/protocol-minimum. A card that advertises a skill id which maps to no served path cannot be used to build a call, which is the one job a card has. The operational probe (§27) exists to catch exactly that.

Develop

npm install
npm run dev        # http://127.0.0.1:8787/health
npm run typecheck
npm test
npm run deploy     # staging (*.workers.dev)

Production (mcp.meshkore.com) deploys from [env.production] in wrangler.toml.

Note: a Cloudflare Worker cannot reach a *.workers.dev host on the same account (error 1042). Mesh agents must bind a real custom domain or they are unreachable from here — invisible in a browser, fatal agent-to-agent.
