Que pouvez-vous faire avec Omniseal ?

  • seal_files: conceal a secret file inside a supported cover.
  • retrieve_secret_file: recover the hidden file using its private seed.
  • verify_sealed_file: check seal integrity, without a seed.
  • remove_hidden_file: create a new clean cover using the private seed.

Installation

Ajoutez ceci à la configuration MCP de votre client (Claude Desktop : claude_desktop_config.json ; Cursor : .cursor/mcp.json ; VS Code et les autres utilisent la même forme « mcpServers »).

Remote (streamable-http)
Claude Code 
claude mcp add --transport http omniseal 'https://api.purecipher.com/mcp?platform=claude'

Omniseal MCP service

Seal, retrieve, verify, and remove hidden files using PureCipher Omniseal.

Connect

Remote Streamable HTTP endpoint:

https://api.purecipher.com/mcp?platform=claude

No account, OAuth, or API key is required for the current public endpoint. For Cline setup, see llms-install.md. Other MCP clients can use the same endpoint with their HTTP transport configuration.

Tools

  • seal_files: conceal a secret file inside a supported cover.
  • retrieve_secret_file: recover the hidden file using its private seed.
  • verify_sealed_file: check seal integrity, without a seed.
  • remove_hidden_file: create a new clean cover using the private seed.

Original input files are preserved. This repository contains the MCP connection documentation configuration and instructions. The hosted service executes the Omniseal SDK.

Inputs and output limits

Each file argument contains file_name and exactly one of download_url (a service-reachable HTTPS URL) or content_base64 (exact file bytes). Local paths and chat attachments are not automatically uploaded.

Selected file contents and the operation seed are processed by PureCipher's hosted service. Use an Omniseal seed, never an account password or API credential. Inputs are limited to 6 MB per file and 10 MB combined for sealing. Responses are limited to 140,000 serialized characters, typically about 100 KB of output bytes. Outputs are binary MCP resources, not hosted download links. Client-side binary rendering and saving have not yet been verified end to end.

The service URL is https://api.purecipher.com/mcp?platform=claude. The query selects the existing compatible file schema; it does not send files to Anthropic. The service is publicly reachable and requires no authentication.

Validation

Validated with Gemini CLI 0.63.0: installation and MCP connection succeeded. All four live MCP operations passed synthetic PNG/PDF tests, including exact recovery of the secret bytes. Model-mediated execution remains unverified.
