BlueSky with pdsx

Use the pdsx MCP tools (list_records, get_record, create_record, etc.) for BlueSky tasks.

Quick Reference

Task	Tool	Example
get a post	`get_record`	`get_record(uri="at://did:plc:xxx/app.bsky.feed.post/abc123")`
list someone's posts	`list_records`	`list_records("app.bsky.feed.post", repo="handle.bsky.social")`
get a profile	`get_record`	`get_record(uri="app.bsky.actor.profile/self", repo="handle.bsky.social")`
create a post	`create_record`	`create_record("app.bsky.feed.post", {"text": "hello"})`

Following Threads

Threads span multiple users. Pattern:

Get the root post to see its content and who posted it:

get_record(uri="at://did:plc:xxx/app.bsky.feed.post/abc123")

List the OP's posts to find replies:
```
list_records("app.bsky.feed.post", repo="did:plc:xxx")
```
Look for posts with reply fields pointing back to the thread.
Extract DIDs from the URIs (format: at://DID/collection/rkey)
Query each participant's posts for their contributions to the thread:
```
list_records("app.bsky.feed.post", repo="did:plc:other")
```
Filter the results locally to find posts where reply.root.uri matches the thread root.

Collections

Collection	Purpose
`app.bsky.feed.post`	posts
`app.bsky.actor.profile`	profile (rkey is always `self`)
`app.bsky.feed.like`	likes
`app.bsky.feed.repost`	reposts
`app.bsky.graph.follow`	follows

Post Structure

Posts reference other posts via reply:

{
  "text": "reply text",
  "reply": {
    "root": {"uri": "at://did/collection/rkey", "cid": "bafyrei..."},
    "parent": {"uri": "at://did/collection/rkey", "cid": "bafyrei..."}
  }
}

reply.root - thread's original post
reply.parent - immediate parent being replied to

Creating Posts

Simple:

create_record("app.bsky.feed.post", {"text": "hello world"})

Reply (requires both uri AND cid from the parent/root posts):

create_record("app.bsky.feed.post", {
    "text": "my reply",
    "reply": {
        "root": {"uri": "at://...", "cid": "..."},
        "parent": {"uri": "at://...", "cid": "..."}
    }
})

Gotchas

strongRef needs uri AND cid - when creating replies, you need both from the parent post
profile rkey is always self - use app.bsky.actor.profile/self
byte indices for facets - links/mentions use UTF-8 byte positions, not character positions
