# SIGNLD MCP Connector

Machine-readable mirror of https://signld.ai/docs/integrations/mcp

## Summary

The SIGNLD MCP connector is a Model Context Protocol server that connects Claude, or any
MCP-compatible client, to a SIGNLD workspace. It gives the client read-only access to your connected
business systems and lets it author your own SIGNLD layer: the Knowledge Graph, Decision Topics,
charts, and dashboards. Every answer is traced back to the source system it came from.

Token savings: a general AI guesses at your business and you re-prompt it until it is close, paying
for every pass. SIGNLD gives the model your business context up front, so it answers from your
connected data on the first pass. Fewer re-prompts, lower token spend.

## Requirements

- A SIGNLD workspace. Free forever plan, no credit card, or a 14-day trial for full access.
- An MCP-compatible client such as Claude.

## Connect

1. Create or sign in to your SIGNLD workspace at https://app.signld.ai
2. Add a custom MCP connector in your client with the server URL https://app.signld.ai/api/mcp (or install from https://smithery.ai/servers/signld/mcp-server)
3. Authenticate to connect your workspace.
4. Start asking questions. The client reads your Knowledge Graph first, then your data.

## Data and safety

Source systems are never written to. Data access and SQL are read-only. The only writes go to your
own SIGNLD layer: the Knowledge Graph, Decision Topics, charts, and dashboards. Deleting a Knowledge
Graph node is the single destructive action and is clearly labeled. Your data stays yours.
