The Bluesky MCP server thatdrinks from the firehose for you
Octolens monitors Bluesky posts for your keywords, scores every match with AI, and serves clean mentions to Claude, ChatGPT, and Cursor over MCP. The network is refreshingly open — the monitoring layer is still on you, unless it's on us.
5-minute setup • OAuth sign-in, read-only • MCP on every planThe dev-tools crowd here is so much better than the old place. Also: finally found a monitoring tool my agents can query directly. Feels like the future.

Open Network, Unsolved Monitoring
Bluesky gives developers real access — a full firehose and an actual search endpoint. That's the raw material for monitoring, not the monitoring.
The firehose is everything, literally
The AT Protocol firehose streams the entire network — every post, from everyone, forever. Free and open, and entirely your job to filter, store, dedupe, and keep the consumer running when the stream hiccups.
Search is a query, not a monitor
searchPosts answers keyword queries within rate limits — it doesn't watch. No push, no alerts, no relevance or sentiment scoring. Continuous coverage means a poller you build, run, and babysit.
Bluesky is one shard of the conversation
Your audience split across networks. A Bluesky-only monitor sees Bluesky's fraction — the same discussion continues on X, Reddit, and HN, and the pieces only make sense together.
Octolens consumes the network for you, keeps only what matches your keywords, scores it with AI, and serves it to your assistant next to mentions from 15+ other platforms — one server, one conversation.
From Firehose to Answer in Your AI Tool
One pipeline: Octolens does the collection and filtering, MCP does the delivery. You just ask.

Bluesky MCP Server & Monitoring, Answered
Setup, coverage, and AT Protocol questions — everything about monitoring Bluesky from Claude, ChatGPT, or Cursor.
Openness solves access, not monitoring. The firehose streams the entire network unfiltered; searchPosts answers queries but watches nothing. Octolens runs the continuous, filtered, scored layer on top — and serves Bluesky next to X, Reddit, HN, and 15+ other sources in one MCP server.
Public posts across the whole network, matched by keyword — not just accounts you follow or feeds you've built. Mentions from communities you've never heard of are usually the interesting ones.
No. Octolens monitors public network data on its side — you configure keywords and connect the MCP server with a browser sign-in to your Octolens account. You'll only want your own Bluesky account for replying, which stays a human job.
Yes — that's the point of one server for all sources. Ask your assistant to compare mentions across bluesky and twitter in a single prompt: volume, sentiment, and which conversations exist on one network but not the other.
Depends on your plan: hourly refresh on Pro ($199/mo, or $159/mo billed annually), real-time on Scale ($599/mo, or $499/mo billed annually).
Yes. Add competitor names and category phrases as keywords — early-adopter networks like Bluesky often discuss switching and alternatives before the sentiment shows up anywhere else.
Claude Code, Claude Desktop and Web, ChatGPT, Cursor, and any other MCP-compatible client. It's one remote server URL with OAuth sign-in — there's no API key to manage and nothing to run locally.
Every new keyword gets a 7-day backfill, then collects continuously — your archive builds from the day you add a keyword. That's enough history for trends, sentiment shifts, and share-of-voice over time.

Add your keywords, connect the MCP server, and ask your assistant what Bluesky is saying about you — all inside the 7-day free trial.
