Token Compressor MCP

Remote MCP server for Claude / Claude Cowork that compresses long context, stores compact reusable summaries, retrieves relevant context by title/tag/query, estimates token savings, and deletes stored records.

Tools

• compress_context — compress pasted text without saving it
• save_context — save raw text and a compressed summary
• retrieve_context — retrieve saved compressed context by query, tag, title, or ID
• list_contexts — list saved records
• context_stats — show estimated savings
• delete_context — delete one record
• clear_contexts — delete all records

Retrieve the compressed context for Test Context.

Privacy note

This starter uses in-memory storage. Saved records disappear when the process restarts. That is intentional for a safer first version. Do not store confidential company data in a personal/free cloud server unless approved.
