Best alternatives to mcprobe in 2026
When you connect an AI agent to a new tool or plugin (an "MCP server"), you're trusting that its description and behavior are exactly what they claim to be. That trust can be abused: a malicious or careless MCP server can smuggle hidden instructions into its tool descriptions to manipulate the AI, or expose file paths and resources it shouldn't. mcprobe is a scanner that inspects an MCP server's tool descriptions, schemas, and resource URIs and flags that kind of problem before you plug it into a live agent. It's a single, dependency-free binary that ships as open source under the MIT license. It detects 18 distinct prompt-injection patterns, checks for "tool shadowing" (where one server's tools silently override another's), flags path-traversal and resource-exposure issues, and can snapshot a server's current state as a baseline to detect configuration drift later. Results can be exported as SARIF for CI/CD pipelines, and it supports stdio, HTTP, and SSE transport types — covering the common ways MCP servers are actually deployed.

#4
Privacy-first browser side panel AI assistant that works with any model or agent and anonymizes sensitive data before it leaves your browser.
chatpanel.net
- ✓ Works with any AI model or agent — in-browser, local, cloud API, or coding agents like Claude Code/Copilot
- ✓ Anonymizes sensitive data (emails, phone numbers, card numbers) before it leaves your browser, restores it in the reply
#5
Open-source, developer-first privacy and cookie-consent infrastructure with headless consent flows and version-controlled policies.

- ✓ Révocation ciblée sans tuer tout le processus
#10
A free Python command-line tool that checks a website's HTTPS certificate and tells you exactly what's wrong with it — expired, untrusted, wrong hostname — instead of a generic connection error.
github.com
- ✓ Zero dependencies, easy to drop into bare servers or containers
- ✓ Detailed diagnostics rather than a generic 'connection failed'
#11
An open-source trust-boundary gateway that sits in front of OpenAI, Anthropic and Gemini API traffic to redact PII, enforce rate limits, and track usage without touching your app code.
github.com
- ✓ Single gateway covering OpenAI, Anthropic and Gemini without SDK changes
- ✓ Comprehensive PII detection and redaction
