Cloud MCP Relay

Connect AI to Sysero.
Keep your documents secure in Sysero.

SyseroMCP is a stateless cloud relay that lets MCP-compatible AI clients work with your Sysero platform — document search, conflict checking, document assembly, reports, and workflow creation — without any document content ever leaving your Sysero environment.

Zero document storage

The relay is stateless. No document content, no search indexes, no bearer tokens, and no end-user data is ever persisted on the cloud.

Your identity, your permissions

Users sign in with your own identity provider via OAuth 2.1 and PKCE. Every tool call runs inside Sysero under that user’s own permissions.

No inbound firewall changes

The on-premises agent dials out to the relay on an outbound connection. Nothing needs to be opened up to the public internet at the firm.

How the connection works

A single, standards-based request path from your AI client to your own Sysero installation.

1

User signs in

The AI client walks the user through an OAuth 2.1 + PKCE flow against your enterprise identity provider.

2

Relay authenticates

Bearer tokens are validated on every request and the user is resolved to a tenant by their verified email domain.

3

Request forwarded

The relay forwards the operation over the persistent outbound channel the on-premises agent has already established.

4

Sysero executes locally

Your on-premises Sysero installation runs the operation under the user’s own permissions and streams the result back.

MCP Tools

Everything your AI needs to be useful

Fifteen MCP tools covering search, conflicts, document assembly, reporting, workflow creation, and project management. Every tool is self-describing and scoped to the user’s own Sysero permissions.

sysero_ping

Health check across all connected on-premises installations.

sysero_search_documents

Full-text and semantic search of the document store.

sysero_get_document

Retrieve the full content and metadata for a document.

sysero_conflict_check

Run a Sysero conflict check against a party or company.

sysero_list_templates

List the document assembly templates available to the user.

sysero_get_template_fields

Return a template’s full field schema and a worked example.

sysero_fill_template

Assemble a Word or PDF document from a template and a payload.

sysero_list_reports

List Sysero reports the user is permitted to run.

sysero_run_report

Execute a report and return the Excel result via a one-time URL.

sysero_list_applications

List applications in which the user can start a workflow.

sysero_get_application_fields

Return an application’s field schema for item creation.

sysero_start_workflow

Create a new item in a Sysero application and start its workflow.

sysero_who_am_i

Identify the current user across all connected Sysero tenants.

sysero_list_projects

List Sysero projects (curated matter or item groups) the user can see.

sysero_get_project_content

Return the items inside a Sysero project, including attached file summaries.

Built for security review

SyseroMCP implements the MCP Authorization Specification (2025-11-25) in full, with data-handling guarantees designed for law firms and their security teams.

Standards implemented

  • OAuth 2.1 with mandatory PKCE (S256) — implicit and hybrid flows are not supported
  • RFC 8414 Authorization Server Metadata published at the standard well-known path
  • RFC 9728 Protected Resource Metadata with zero-configuration discovery
  • RFC 7591 Dynamic Client Registration for MCP clients that support it
  • HTTPS-only endpoints with HSTS asserted in production

Data handling guarantees

  • No document content, search results, or tokens are ever written to disk on the relay
  • Transient document and report outputs expire after five minutes and never survive a restart
  • Tenant shared secrets are encrypted at rest and compared in constant time
  • Fail-closed authorisation — without identity provider config, every request is denied
  • Rate limiting, brute-force protection, and log sanitisation applied on every public endpoint
