Working with Claris MCP and Claude Desktop

15 hours ago15 hr

Hi all,

I have some questions about working with Claris MCP and Claude Desktop.

Q1 : How do I add additional tables to an existing connection in Claris MCP? The documentation says I can add connections in Editing state, but my interface only shows 'generate configuration' with no option to add or edit connections.

Q2 : How do I prevent Claris MCP from returning large container/media fields in update tool responses? The full record data exceeds 1MB and causes Claude errors, but tool descriptions and schema parameters don't control the response size.

Q3 : When using OData vs Data API with Claris MCP, OData returns all fields including large container fields that exceed 1MB, whereas Data API allows managing this through special layouts. What's the recommended approach to handle large container fields in Claris MCP - should I use Data API instead, or is there a way to configure OData to exclude container fields?

Q4 : When setting up Claris MCP connections, how should I choose which tables/relationships to include from a large FileMaker relationship graph if editing the connection later isn't available? What's the best strategy for selecting items initially without excluding tables I might need later?

Q5 : Claris MCP Developer Tools Issue - Simple Summary

Problem: Documented Developer Tools for connection management are not being exposed by the Claris MCP server.

What We Need: Access to connection management tools (specifically update_filemaker_connection) to add tables to existing connections without deleting them.

Current Status:

Context is in Editing state ✅

Claude Desktop configured with "Always available" tool access ✅

Only 7 tools appear (6 connection-based + 1 developer tool)

Connection-management tools completely absent ❌

Missing Tools:

get_connections

add_filemaker_connection

update_filemaker_connection

remove_connection

Other connection management tools

Impact: Cannot add tables to existing connections or modify connection configuration as documented.
