About SEAL

Large files and secrets between people and agents, never through the chat or the model.

Configuration

Local server config is the same for every client. Copy it into your client’s MCP config file.

mcp.json · Universal config
{
  "mcpServers": {
    "net-seal": {
      "command": "npx",
      "args": [
        "-y",
        "sealnet-mcp"
      ]
    }
  }
}
Run commandnpx -y sealnet-mcp

Local servers need a runtime on your machine (e.g. Node.js 18+). Config file locations differ by client; see your client’s docs.

ParameterTypeRequiredDescription
tostringNoThe recipient's SEAL address (43 characters: `sealnet-mcp pubkey`, `seal keygen`). REQUIRED for mode=forward; not read in mode=handoff. Refused in mode=inbox: the address there is the connected owner.
burnbooleanNoBurn ciphertext after last read.
mimestringNoOverride the auto-detected MIME type (encrypted into the metadata bundle; drives the recipient's inline-render whitelist).
modeenumNoWhere the link goes. Without it: `inbox` when this agent is connected to the user's inbox (seal_pair, or SEAL_OWNER), else `handoff`. `inbox` needs a connected owner (`owner_not_paired` otherwise) and takes no `to`.inbox | handoff | forward
pathstringNoAbsolute path to the file or folder to share. A folder is sent as one `<folder>.zip` of its regular files (symlinks are skipped). The server streams it from disk; you never read the content yourself. Required unless `payment` is given.
tierenumNoAbove the free limit only: the tier the user pays for once by card, a code of `limits.json::SEAL_TIERS` (prices and terms: seal.net/pricing). Default: the smallest that fits.5gb | 50gb | 500gb
expireenumNoHow long the link lives: one of `limits.json::ttl_options`. Default 5m; in handoff mode a file or folder over 100 MB defaults to 1d. Forward mode allows at most 30m. Above the free limit (a paid tier): 1d or 7d, default 1d.5m | 30m | 1h | 1d | 7d
paymentstringNoHandle of a share waiting for its payment: wait for it and finish the upload.
max_readsintegerNoMaximum number of downloads. Forward mode locks this to 1.

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.
