What is this MCP server?
- Policy-enforcing MCP proxy—central gate for multiple downstream MCP servers
- Portable evidence output for reviews, compliance asks, and incident response
- Registry title Assay MCP Server v3.9.2 with github-release publisher workflow
- stdio mcpb package with version-aligned identifier and SHA256
- Same Rul1an/assay repository family as the Assay firewall CLI entry
- Registry version 3.9.2
- Publisher workflow assay-release-workflow on github-release channel
- 1 stdio mcpb package entry with fileSha256 in server.json

What problem does it solve?
Scattering MCP servers behind the agent with no central policy makes it hard to prove what was executed or to stop risky tools consistently.
Who is it for?
Builders running several MCP backends who want one security choke point and exportable proof of agent tool usage.
Skip if: Simple one-server MCP setups with no compliance needs, or teams wanting only host-level firewall rules without MCP awareness.
What do I get? / Deliverables
Once registered, clients talk to one enforcing proxy that applies policy and produces portable evidence you can archive or share.
- Central policy-enforcing MCP proxy endpoint
- Portable evidence outputs from proxied sessions
- v3.9.2 pinned MCPB registration

How it compares
MCP policy proxy with evidence export, not a curated skill marketplace or LLM prompt pack.
Common Questions / FAQ
Who is Assay MCP Server for?
Developers shipping agent products who need a dedicated MCP proxy with enforceable rules and evidence artifacts, not just ad-hoc logging.
When should I use Assay MCP Server?
Use it when you are centralizing MCP access for multiple tools, preparing security documentation, or aligning with the fuller Assay firewall workflow at v3.9.2.
How do I add Assay MCP Server to my agent?
Install io.github.Rul1an/assay-mcp-server from the MCP registry using the v3.9.2 linux.mcpb identifier, configure stdio in your client, and route other servers through the proxy per Assay repo docs.
