"Creating the Best General-Purpose Agent" matching MCP servers:

Enables structured learning with a verified loop: define goals as observable claims, learn through teach-lab-test-gate per claim, and get independently graded by an adversarial examiner to ensure genuine progress.

Multi-agent sales email generation server that creates, evaluates, and sends personalized sales emails via SendGrid, using AI to craft diverse email styles and select the best one.

Hosted MCP server (OAuth, no API keys) that makes short drama series (micro-dramas, sitcoms, K-drama style, any language) and other short vertical videos from Claude, ChatGPT or Codex, with the same cast every episode.

Provides tools for vehicle service search, mechanic matching, and booking generation as part of a multi-agent AI system for roadside assistance.

MCP server exposing statistical regression testing for LLM agents as a "run" tool: p-value, effect size, and confidence interval on whether agent behavior actually changed.

Calibrd Agent scores a job against your CV from inside your assistant: fit, seniority gaps, ATS/recruiter CV read, and predicted interview questions. Reports are free (3/day); cover letter and a time-boxed pass unlock when you ask, voice mock stays in Calibrd.com/workspace.

MCP server that packages DeepSeek agents as callable tools, offering a bare model for quick Q&A and a full agent capable of executing real coding and file-modifying tasks in a workspace.

A lightweight MCP server that enables text agents to analyze images and videos using OpenAI-compatible vision models, with tools for image analysis and video frame extraction.

MCP server for AI agent observability, providing trace and span logging, search, latency/tokens/cost metrics, and anomaly detection using an in-memory buffer.

An MCP server that enables interaction with property-driven machine learning experiment pipelines, including listing experiments, retrieving configs, comparing runs, and executing experiments with approval gates and full tracing.

An MCP server that bridges Claude Code with Antigravity CLI using a Swarm Agent architecture to optimize local development workflows and minimize LLM token costs. Includes a web UI for monitoring agent workflows.

Enables MCP clients to query and diagnose machine-learning training runs through read-only tools for listing experiments, reading configurations and final metrics, comparing runs, sampling metric curves, and detecting training failures.

An MCP server that enables AI agents to verify facts, check market and on-chain data, search the web, and run AI text tasks through five general-purpose tools, with pay-per-call USDC settlement on Base via x402 and no API key required.

Enables AI agents to convene meetings and collaborations with personas across multiple LLM providers, run local meetings via the Claude CLI, and make direct chat completions to supported providers.

Enables routing tasks across Cursor agents and external LLM backends through chat, while managing local models, write allowlists, and asynchronous workflows.

Aggregates tools from multiple MCP servers, acting as a proxy to provide unified access to various AI agents and tools.

Enables reusable role-based agents, solo execution, and bounded multi-agent discussions with independent proposals, peer critiques, judge consensus, revision rounds, token budgeting, and SQLite audit logging.

Enables creating and deploying Agentforce agents to Salesforce by gathering requirements and generating agent metadata.

Enables MCP clients to run superposition-based problem solving, decompose problems into orthogonal branches, force lateral tunneling past bottlenecks, and retrieve live status for long-running sessions.

Enables agents to purchase and use compute resources on Robinhood Chain via x402 payments. Provides tools for thinking, renting GPUs, checking balances, and viewing the compute menu.

A neutral verification court for AI tools that ranks MCP servers by executing them against ground truth and recording results. Enables agents to consult execution records, contribute verdicts, and challenge claims.

Turn any API into an MCP server. Query in English. Get results—even when the API can't.

Enables compiling typed decision queries into the smallest decision-sufficient evidence context with machine-checkable Context Certificates, providing auditable executable-biology inference through local MCP tools.

Astrology API plugin for Claude Code, Cursor and Agent Plugins clients: a skill plus the keyless docs MCP across 18+ domains. One install, one key.

Enables model routing and contract validation through two read-only MCP tools: route_models for evaluating routing payloads and explain_contract for returning the stable routing and custody boundary.

An MCP server that lets agents act as the person who added them, giving them identity, shared context (data, documents, goals, calendar, skills), and a place to publish apps and pages behind sign-in. It also brokers access to models, data APIs and other tools' MCP servers through one key, with consent prompts, per-person access checks and encrypted credentials as guardrails.

ai-jobs-agent MCP server: Exposes an autonomous job-detection agent's data to MCP clients, offering tools to search jobs, retrieve job details, view detection-latency statistics, and trigger on-demand sweeps

Enables document-based Q&A with multi-modal RAG, hybrid retrieval, knowledge graph reasoning, and multi-agent orchestration via MCP tools.

A download tool for AI agents that wraps aria2 with safety rules and MCP server support, enabling reliable downloads without false positives.

Provides deterministic JSON repair and JSON Schema validation for malformed AI agent outputs, safely fixing unambiguous errors without an LLM and refusing ambiguous cases.
