Overview

AI-generated overview

Remote MCP endpoint that classifies text into topic categories with confidence scores, readability metrics and content type, paid per call via x402.

What you can do
  • Classify a block of text into topic categories (tech, finance, health, sports, politics, entertainment, science, business) or custom categories, returning the top three with confidence scores.
  • Get detected language, Flesch-Kincaid readability level and content type (article, review, tutorial, news) alongside the classification.
  • Use the results for content organization, tagging and routing; the README points to separate services for sentiment and summarization.
When to use it
Useful when an assistant needs to tag, route or organize incoming text by topic and wants a hosted classifier rather than its own heuristics. It is a single-purpose service, so it only makes sense if you are willing to pay per call in crypto.
Requirements
A remote MCP endpoint reached over SSE; no API key, signup or environment variables. Calls are paid per request in USDC on Base L2 through the x402 protocol, so an x402-aware client with a funded wallet is needed to complete the payment challenge. The README lists $0.012 per classify call.
Before you install
Every call costs money in USDC on Base and requires a wallet that signs payment challenges, so spending limits and wallet key handling matter. Text you submit is sent to a third-party service. The README states there is no signup or API key, which also means no per-user access control or usage cap beyond your wallet balance.

Installation

In SourceWeft

  1. Open Text Classifier API in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via SSE. 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/io.github.Br0ski777%2Ftext-classifier/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

Other MCP clients

Add this to your client's mcpServers config.

README

Text Classifier API

[MCP Server] [x402] [License: MIT]

Classify text into categories with confidence scores, readability analysis, and content type detection. Pay-per-call via x402 (USDC on Base L2) -- no API key, no signup, no rate-limit wall.

Part of the klymax402 marketplace -- 100 x402 micropayment APIs for AI agents, one wallet, USDC on Base.

Quickstart -- MCP

Add to your MCP client config (Claude Desktop, Cursor, ElizaOS, etc.):

json
{  "mcpServers": {    "text-classifier": {      "url": "https://text-classifier.api.klymax402.com/mcp"    }  }}

Quickstart -- HTTP (x402)

bash
curl -X POST "https://text-classifier.api.klymax402.com/api/classify" \  -H "Content-Type: application/json" \  -d '{"text":"..."}'# -> 402 Payment Required, with an x402 payment challenge in the response body

Any x402-aware client (@x402/fetch, x402-agent-tools, ATXP) handles the 402 -> sign -> retry cycle automatically.

Tools

text_classify_content

Use this when you need to categorize text into topic categories (tech, finance, health, sports, politics, entertainment, science, business). Returns top 3 categories with confidence scores, detected language, Flesch-Kincaid readability level, and content type (article/review/tutorial/news). Ideal for content organization, tagging, and routing. Do NOT use for sentiment — use text_analyze_sentiment. Do NOT use for summarization — use ai_summarize_text.

Score

50% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 daysRequired25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declaredRequired10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
