Claude MCP session reaching max conversation limit after just 3 prompts

[goddard@…]

The following bug report has been submitted:
Platform:        macOS-26.0.1-arm64-arm-64bit
ChimeraX Version: 1.11.dev202510170018 (2025-10-17 00:18:50 UTC)
Description
Claude controling ChimeraX is hitting a maximum conversation length limit after just 3 prompts.  Using mcp_server bundle from 10 AM today.   Never saw this before in earlier mcp_server versions with conversations with 30 prompts.  The first conversation Claude asked to save an image but I did not respond, in the second short conversation I let it save one image.

Here is the Claude log of that second conversation:

Can you show me a human opioid receptor with fentanyl?
I'll help you visualize a human opioid receptor with fentanyl bound to it. Let me open a structure from the Protein Data Bank.
C
Open structure
I've opened structure 5C1M, which is a crystal structure of the human mu-opioid receptor. However, this structure contains BU72 (a different opioid agonist), not fentanyl. Let me search for a structure with fentanyl specifically.
C
Run command
fentanyl opioid receptor PDB structure
10 results








Perfect! I found it. Structure 8EF5 contains the human mu-opioid receptor bound to fentanyl in complex with a G protein RCSB PDBScienceDirect. Let me open this structure for you.
C
Open structure
Excellent! I've opened the structure. Now let me create a nice visualization showing the receptor with fentanyl. Let me first hide the G protein complex and focus on the receptor and fentanyl.

Now let me capture the view to show you what this looks like:

Great! Here's what you're looking at:
This is the structure of the human mu-opioid receptor (shown in blue and cyan, there are two copies) bound to fentanyl (shown in magenta/pink spheres in the center). The mu-opioid receptor is the primary target through which fentanyl and other opioids produce their effects - both pain relief and the dangerous side effects.
This structure was determined using cryo-electron microscopy and shows how fentanyl binds within the receptor's binding pocket RCSB PDBScienceDirect. You can see the fentanyl molecules nestled in the binding sites of each receptor copy.
The structure also includes the G protein complex that the receptor activates, though I've hidden that part to focus on the receptor and fentanyl binding. Would you like me to show you different views or highlight specific interactions between fentanyl and the receptor?
Can we replace fentanyl with carfentanil?
I'll search for a structure with carfentanil and the opioid receptor.
carfentanil opioid receptor PDB structure
10 results








Unfortunately, I don't see an experimental crystal or cryo-EM structure of carfentanil bound to the opioid receptor in the PDB database. However, computational studies have predicted how carfentanil binds to the mu-opioid receptor using molecular dynamics simulations NCBI.
What I can do instead is:
Keep the current fentanyl structure - This already shows you the binding mode which is very similar to carfentanil
Build a model of carfentanil - I could create a molecular model of carfentanil and overlay it on the fentanyl position based on the computational predictions
Show a different opioid - I could load structures with morphine or other opioids if you'd like to see how different drugs bind
Would you like me to try option 2 (building a carfentanil model in the binding site), or would you prefer to see a different comparison? The structural difference between fentanyl and carfentanil is actually quite small - carfentanil has a methyl ester group where fentanyl has other substituents, making it about 100 times more potent.
Yes, please build the model.
I'll build a carfentanil molecule and position it in the binding site where fentanyl currently is. Let me start by creating the molecular structure of carfentanil.
Generate 3D structure of carfentanil using RDKit
Let me install RDKit first:
Install RDKit for molecule building
Great! Now let me generate the carfentanil structure:
Generate 3D carfentanil structure
Now I need to align carfentanil to the fentanyl position in the receptor. Let me first extract the fentanyl coordinates from the structure:
C
Run command
Let me try a different approach - I'll use ChimeraX's temporary directory:
Create writable temporary directory
C
Run command
