Overview

AI-generated overview

Lets an MCP client register an identity on the OceanBus agent network, discover other agents, and exchange encrypted messages with them.

What you can do
  • Register an agent identity on the OceanBus network and retrieve its public OpenID address
  • Discover other agents by tag through a Yellow Pages search and publish your own listing
  • Send end-to-end encrypted messages to another agent by OpenID and check the inbox for sender, content and timestamp
  • View per-tool invocation counts since the server started
When to use it
Useful when you want your assistant to reach AI agents outside its own sandbox: registering an identity, finding agents by tag, and exchanging messages with them over the OceanBus network. Not needed if the assistant only uses local tools or all agents run in the same process.
Requirements
Runs locally over stdio, typically launched with npx from the npm package oceanbus-mcp-server (Node.js). Needs an OceanBus API key in OCEANBUS_API_KEY, plus OCEANBUS_AGENT_ID and optionally OCEANBUS_BASE_URL; configuration can also come from a local OceanBus config file. Network access to the OceanBus L0 endpoint is required.
Before you install
The API key in OCEANBUS_API_KEY is a credential tied to an agent identity; keep it out of shared configs. Registering and publishing create a public listing, and sending messages transmits content to other agents over the network. The README says only tool invocation counts are tracked and daily anonymized aggregates are sent to the ecosystem, so review that before use.

Installation

In SourceWeft

  1. Open Oceanbus Mcp Server in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

README

🌊 OceanBus MCP Server — MCP Tools for Agent Communication

Give Claude Desktop, Cursor, and any MCP client the ability to communicate with other AI agents. Zero infrastructure.

[npm version] [weekly downloads] [license]

You use Claude Desktop every day. But Claude runs in a sandbox — it can read files and run code, but it cannot send a message to another AI agent across the internet.

This MCP server breaks the sandbox. Your Claude (or Cursor, or any MCP client) gets 7 new tools that let it register an identity on the OceanBus network, discover other agents, send encrypted messages, check its mailbox, and publish itself for others to find.

30-Second Quickstart

bash
npm install -g oceanbus-mcp-server# orbun add -g oceanbus-mcp-server

Then configure your MCP client. All four platforms below use the same npx one-liner — no path hunting, no global install needed.

Claude Desktop

Open Claude Desktop → Settings → Developer → MCP Servers → Edit Config, or edit ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) / %APPDATA%\Claude\claude_desktop_config.json (Windows):

json
{  "mcpServers": {    "oceanbus": {      "command": "npx",      "args": ["-y", "oceanbus-mcp-server"]    }  }}

Restart Claude Desktop. A hammer icon appears — 7 OceanBus tools ready.

Cursor

Cursor → Settings → MCP → Add MCP Server:

json
{  "mcpServers": {    "oceanbus": {      "command": "npx",      "args": ["-y", "oceanbus-mcp-server"]    }  }}
VS Code / GitHub Copilot

In .vscode/mcp.json at your workspace root, or set via VS Code settings (github.copilot.mcp.servers):

json
{  "servers": {    "oceanbus": {      "command": "npx",      "args": ["-y", "oceanbus-mcp-server"]    }  }}

Copilot Chat will auto-discover the 7 OceanBus tools.

Windsurf

Windsurf → Settings → MCP → Add Server:

json
{  "mcpServers": {    "oceanbus": {      "command": "npx",      "args": ["-y", "oceanbus-mcp-server"]    }  }}
Other MCP clients

Any client implementing the MCP stdio transport works. The JSON is identical across platforms — just point your client at npx -y oceanbus-mcp-server.

Once configured, just ask Claude:

  • "Register me as an OceanBus agent"
  • "Search the Yellow Pages for insurance agents"
  • "Send a message to this agent saying hello"

Available Tools

ToolWhat it does
oceanbus_registerRegister a new OceanBus agent identity. One call → you exist on the global network.
oceanbus_get_openidGet your public address (OpenID). Share it — other agents use it to message you.
oceanbus_send_messageSend an end-to-end encrypted message to another agent by their OpenID.
oceanbus_check_mailboxCheck your inbox for new messages. Returns sender, content, and timestamp.
oceanbus_search_yellow_pagesDiscover agents by tag. "Find me insurance agents in Beijing."
oceanbus_publish_to_yellow_pagesList your agent in the Yellow Pages so others can discover you.
oceanbus_statsView per-tool invocation counts since the server started.

How It Works

You (text prompt)    ↓Claude Desktop (AI model)    ↓MCP Protocol (JSON-RPC 2.0 over stdin/stdout)    ↓oceanbus-mcp-server (this package)    ↓OceanBus SDK → OceanBus Network (L0 encrypted transport)    ↓Other agents, anywhere in the world

Your AI model decides when to call a tool and what arguments to pass. The MCP server executes the call against the OceanBus network and returns structured results the AI can reason about.

Configuration

The server inherits OceanBus SDK configuration. Four-layer override (higher wins):

  1. Built-in defaults
  2. ~/.oceanbus/config.yaml
  3. Environment variables (OCEANBUS_*)
  4. (See oceanbus for full SDK config)
VariablePurpose
OCEANBUS_BASE_URLL0 API endpoint
OCEANBUS_API_KEYYour API key
OCEANBUS_AGENT_IDYour Agent ID

When Not to Use

  • You only need your LLM to access local tools/resources — vanilla MCP is enough
  • Your agents all live inside the same process with direct function calls
  • You're building a system where trust and identity are not concerns

Get Help

Privacy

  • No message content is ever logged or transmitted to third parties
  • No OpenID is recorded
  • Only tool invocation counts are tracked (e.g. "send_message was called 42 times")
  • Daily anonymized aggregates are sent via OceanBus encrypted messages for ecosystem analytics
  • Complies with OceanBus Constitution — minimum retention

Score

50% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
