The TypeScript SDK for AgJSON — the open, typed transport for normalized agent-framework I/O, unopinionated about storage and rendering. Open source (MIT).

Install

npm install @silverprotocol/core @silverprotocol/claude-agent-sdk
# or openai-agents / google-adk for other frameworks

Requires Node.js 22.12 or later. The packages are ES modules: import them, or require() them from CommonJS, which Node supports for ES modules from 22.12 on.

Packages

  • `@silverprotocol/core` — the AgJSON types (AgInput, AgEvent,

AgMessage, AgReduceResult), the stateful-per-invoke Normalizer interface (push(native): AgEvent[] / flush(): AgEvent[]), and the normative Reducer and reduce() (stream → object graph).

  • `@silverprotocol/` — per-framework normalizers

(claude-agent-sdk, openai-agents, google-adk, ...) that translate each framework's native e

Questions

What is the @silverprotocol/core MCP server?

TypeScript SDK for AgJSON — the normalized wire format for agent framework I/O

What tools does @silverprotocol/core expose?

12 in total: 10 read-only, 1 that write, and 1 that can delete or overwrite (delete_file). Every one is listed on this page with its risk.

Is @silverprotocol/core safe to connect to an agent?

With care. The audit graded it C (71/100) and found 21 things worth knowing before you trust this server, listed below with the exact line each was found on. Separately from the audit: 1 of its tools can destroy data, so scope the token you give it to what you actually need.

What credentials does @silverprotocol/core need?

It reads ANTHROPIC_API_KEY and GOOGLE_API_KEY from the environment. Give it a token scoped to the least it needs — an agent that can be talked into calling a tool can be talked into calling it with your credentials.

How does @silverprotocol/core run?

It speaks streamable-http, so it runs as a service you connect to over the network. It is published on npm as @silverprotocol/vercel-ai at 0.12.0.

How current is this page?

The grade is for one exact copy of the source (e001ebdf3776), read on 2026-10-12. The repository is watched and re-audited when it changes.
