Search Inside Your S3 Bucket Files Through Your Muse

Through an AnythingMCP File Search connector, your muse can search documents stored in an S3 bucket in plain words, find the page that answers your question, and hand you the file.

What it does

The connector adds 10 tools and only reads. It works with Amazon S3, DigitalOcean Spaces, MinIO, Wasabi, Hetzner Object Storage, and Backblaze B2. AnythingMCP builds a full-text index under the prefix you pick, and keeps it in sync. The muse can search the index by words, find a file by name even when it is typed slightly wrong, read a file by page, and run an exact search for a code or number. It can show a PDF page as a picture and give you the file as a temporary download link. Answers name the file, page, and date, so you can check the source. Nothing is written back to the bucket.

How to use it

1. Make an access key that can only list and read the one bucket you want searched. Never use your account's main key.
2. Start an AnythingMCP account and add the S3 Bucket File Search connector.
3. Enter the endpoint (leave it blank for Amazon S3), the region, the bucket name, the key and its secret, and the prefix to index, for example invoices/.
4. Run the test step and check the list it returns.
5. Scan the prefix, uncheck archive folders you do not want searched, and activate.
6. In Muse, open Settings, then Connectors, and add a custom connector with the address AnythingMCP gives you. Sign in, approve, then ask about the files.

What you need

• A Muse account that can add custom connectors
• An AnythingMCP account with the S3 Bucket File Search connector added
• An S3 bucket, or a compatible store listed above, with a read-only key

What to watch for

• S3 has no real folders. The folders are key prefixes, and the prefix you pick is the limit on what gets indexed. Pick it with care.
• Plans cap the number of files indexed and their size. If the prefix grows past the plan, syncing pauses and newer files may be missing from answers.
• Scanned PDF files with no text layer need a higher plan for character reading. Without it, files are found by name only.
• The cloud service only reaches public endpoints. A private MinIO server needs the self-hosted version on that network. This is a custom connector, and Meta does not review custom connectors. You can disconnect it in Settings at any time. The muse prepares, you decide.
