Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified that this server's namespace belongs to textforagents.com, which also runs its endpoint. That identifies the publisher; it does not make the server's tools safe.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

Remote MCP server that meters sampling requests per server, enforces a fail-closed allowance and scope clamp, and issues pre-connect verdicts.

What you can do: Meter a sampling/createMessage request against a per-server ledger with a fail-closed allowance and scope clamp
Get a pre-connect verdict (allow, caution, deny, insufficient data) for one server from your own measured profile
Read your per-server sampling ledger rows
View and tune your allowance and threshold policy
When to use it: Useful when you want to cap and track how much MCP sampling a given server consumes, or check a server's measured profile before connecting to it. Suited to operators who want a policy-based guard rather than ad hoc limits.
Requirements: Runs as a remote streamable HTTP endpoint at textforagents.com; no packages, environment variables or headers are declared. Metering and verdicts beyond the free allowance are billed through x402 payments, so a payment-capable client is needed for paid use.

Before you install

Metering and verdicts are billed: flat coverage first, then per-call x402 charges (0.002 for metered requests, 0.005 for verdicts after the first 100 free ones per operator). Ledger and policy tools expose your operator's data, so treat access to this endpoint as sensitive. Verdicts depend on your own measured profile and may return insufficient data.

Installation

In SourceWeft

Open Sampling Quota Guard in the dashboard and add it to a workspace.
Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.textforagents%2Fsampling-quota-guard/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Add this to your client's mcpServers config.
