Snapshot Site MCP

Official MCP server for the Snapshot Site API

Tools

  • screenshot
  • analyze
  • compare

These tools are annotated for MCP clients as:

  • read-only
  • idempotent
  • open-world

They also include richer titles, category metadata, and example intents to improve tool selection in Claude Desktop and Cursor.

Two ways to connect

Hosted, with OAuth — point your client at https://mcp.snapshot-site.com/mcp and sign in. There is no local process to run and no API key in your client config; the server resolves your account from the OAuth session.

Local, with an API key — run the package yourself over stdio and provide SNAPSHOTSITEAPI_KEY. The server calls the Snapshot Site API directly.

Either way, calls count against the same plan quota as direct API calls. Nothing is metered differently because it came through MCP.

Credentials

The hosted server needs no credential — you sign in through OAuth and the server resolves your account from the session. Skip this section unless you run the server yourself over stdio.

For local stdio mode you need a Snapshot Site API key.

  1. Sign up for a Snapshot Site Console account.
  2. Create an API key on the API Keys page.

unless you're pointed at a self-hosted or staging instance.

  1. Pass the key to the server as the SNAPSHOTSITEAPI_KEY environment variable.
  2. Leave SNAPSHOTSITEBASE_URL at its default (https://api.prod.ss.snapshot-site.com)

Compatibility

Requires Node.js 20.9 or later. Built against @modelcontextprotocol/sdk v1.28 and tested with Claude Desktop and Cursor over stdio, and with any client that speaks the streamable HTTP transport against the hosted endpoint.

Usage

Not sure which options to use? Preview a capture and its parameters in the Screenshot console playground before wiring them into a tool call.

OAuth discovery flow

What a client does when connecting to the hosted server:

1. Discovery

Claude
  -> GET https://mcp.snapshot-site.com/.well-known/oauth-protected-resource

MCP
  -> responds:
     authorization_servers = https://mcp.snapshot-site.com
2. Authorization

Claude
  -> must know client_id
  -> opens:
     https://mcp.snapshot-site.com/oauth/v2/authorize
     ?client_id=...
     &redirect_uri=https://claude.ai/api/mcp/auth_callback
     &response_type=code
     &code_challenge=...
3. Token

Claude
  -> receives an access token
  -> calls the MCP server:
     POST https://mcp.snapshot-site.com/
     Authorization: Bearer <access_token>

The server then validates the token against the issuer and resolves the account it belongs to before running the tool.

Verifying the deployment

curl -s https://mcp.snapshot-site.com/.well-known/oauth-protected-resource | jq
curl -s https://mcp.snapshot-site.com/.well-known/openid-configuration | jq
curl -i https://mcp.snapshot-site.com/
curl -i -X POST https://mcp.snapshot-site.com/mcp -H 'content-type: application/json' --data '{}'

Manual vs implicit client_id

Shortened. The full README is on GitHub.
