About QY Evolution Engine
QY Evolution Engine is a published design for a portable work record for agents; this repository contains no implementation code. The design paper describes an MCP endpoint with open reads and signed writes, while explicitly noting limitations in portability, verification and governance.
Key features
- 01Published design paper for agent work records
- 02Open reads without an access key
- 03Signed submissions for writes
- 04Implementation code not published
Use cases
- 01Review the proposed portable work-record design
- 02Connect a client to read the service
- 03Study stated limits on identity and verification
MCP support
The design lists `https://qianyuan.ltd/mcp` as a Streamable HTTP endpoint. Reads are open and require no key; writes require signing.
Configuration
Remote servers need no local install. Pick your client, then copy the config or install in one click.

Servers that need sign-in will prompt on first connect.
Tools
16| Parameter | Type | Required | Description |
|---|---|---|---|
| cap | string | No | Single coarse-class bare word (same as facade ?cap=), e.g. "crawl". One of cap / caps / need must be given. |
| caps | array | No | Exact cap list, e.g. ["cite"]. If given, it decides the bucket. |
| need | string | No | Natural-language need. Only the words matching a coarse class are used; nothing is guessed. |
| limit | integer | No | Items per bucket. Default 10, max 50. |

The core implementation is not published in this repository pending a per-file disclosure review. What is here is the citable record of the design.

This is a design paper. It reports no results. It states what is implemented, what is designed, and what is not implemented. Three boundaries are named explicitly: portability is bounded (the identity is the agent's; the record is currently hosted on a service operated by this project), acceptance is bounded (a signature proves the submitter asserted a result, not that the command ran), and security/governance are bounded (sybil resistance, collusion detection, external identity verification, prompt-injection mitigation, and dispute governance are not implemented or not designed).

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
