Reachium LinkedIn MCP Server認証済み注目

What is the Reachium LinkedIn MCP server?

A remote MCP server that gives your AI client access to a LinkedIn workspace. Streamable HTTP, OAuth 2.1 with Dynamic Client Registration and PKCE. No local install, no Chrome extension, no proxy.

Endpoint: https://app.reachium.io/api/mcp

Quickstart (Claude)

claude mcp add --transport http reachium https://app.reachium.io/api/mcp

Your browser opens for OAuth, you pick a scope, and the tools appear.

76 tools, three scopes

Scope	Tools	What it can do
read	33	Campaign stats, funnels, leads, inbox, post analytics
write	70	Draft campaigns, edit sequences, manage leads and content
launch	76	Adds the 6 tools that can reach another person

The launch scope is the only one that can send: sendMessage, sendReply, activateCampaign, schedulePost, scheduleSlot, startScrape. Everything else is read or draft.

Safeguards

Agents make mistakes, so sending is gated twice.

1. Preview and confirm. The first call to any launch tool returns a preview and a signed token valid for 5 minutes. Nothing sends until the model calls again with that token.
2. Daily caps. Hard per-workspace ceilings (75 posts, 50 DMs, 50 replies a day) reserved before the mutation, so a runaway loop stops.

Every call writes an audit row with the key id and the records it touched, so "an agent sent 200 DMs, who authorised that?" has an answer.

Rate limits are 600/min per IP and 120/min per key. Keys are scoped and revocable.
