The publisher's own server: Video Transcript
Overview
Remote MCP endpoint that lets an assistant validate JSON payloads against a bounded JSON Schema 2020-12 subset, read-only and deterministic.
- What you can do
- Validate JSON payloads against a bounded JSON Schema 2020-12 subset
- Return deterministic, read-only validation results for submitted payloads
- When to use it
- Useful when an assistant needs to check that JSON documents conform to a schema, for example while building or debugging API requests and responses, without any write access to your data.
- Requirements
- A remote streamable HTTP endpoint; no local install. A bearer token is required in the Authorization header. A free trial token (20 calls per day) can be requested from the service's trial endpoint.
Installation
In SourceWeft
- Open ELYREON Payload Validator in the dashboard and add it to a workspace.
- Connect Authorization token credentials. They are stored privately and never shown on public pages.
- Enable the server for the chats that should use its tools.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Use with an agent
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/io.github.colt2822%2Fpayload-validator/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Other MCP clients
Add this to your client's mcpServers config.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
