After scoring nearly 40K tools, the data revealed some uncomfortable truths — and one big problem with how we were measuring quality.</p> <h2> The Problem </h2> <p>Our first scoring system evaluated tools on static analysis alone: schema correctness, token efficiency, description quality, security, and install reliability. Five dimensions. One composite quality score.</p> <p>The result: <strong>85.7% of all tools scored Grade B.</strong></p> <p>No differentiation. No motivation to improve. A platform that tells everyone "you're average" is a platform nobody needs.</p> <h2> The Fix: Additive Scoring Model </h2> <p>We rebuilt the system from scratch. The new model recognizes that <strong>real-world adoption matters just as much as code quality.</strong><br> </p> <div class="highlight js-code-highlight"> <pre class="highlight plaintext"><code>Composite Grade = Quality Score (0-100) + Community Bonus (0-60) + Trust Bonus (0-30) </code></pre> </div> <p><strong>Quality Score</strong> — Static analysis of your tool definition. Five dimensions: Schema (25%), Token Efficiency (25%), Description (20%), Security (15%), Install (15%).</p> <p><strong>Community Bonus</strong> — How agents actually gauge reliability. Stars (log-scale, 0-30), Activity recency (0-20), Official/Verified status (0-10).</p> <p><strong>Trust Bonus</strong> — Real execution data. No data = no bonus (not a penalty). Proven tools earn up to 30 extra points.</p> <h3> Quality Floor </h3> <p>Popularity cannot outrank genuine quality. A tool with 10K stars but poor engineering cannot exceed its Quality Floor cap.</p> <h2> The Results（39,762 tools） </h2> <div class="table-wrapper-paragraph"><table> <thead> <tr> <th>Grade</th> <th>Distribution</th> <th>What it means</th> </tr> </thead> <tbody> <tr> <td>B+</td> <td>2.8%</td> <td>Very good — close to A, highly motivated</td> </tr> <tr> <td>B</td> <td>18.1%</td> <td>Good — solid quality, room to grow community</td> </tr> <tr> <td>C+</td> <td>13.8%</td> <td>OK — decent quality, needs promotion</td> </tr> <tr> <td>C</td> <td>54.0%</td> <td>Average — good foundation, no community signal yet</td> </tr> <tr> <td>D</td> <td>10.9%</td> <td>Needs work — quality gaps but still active</td> </tr> <tr> <td>F</td> <td>0.4%</td> <td>Critical — abandoned or serious issues</td> </tr> </tbody> </table></div> <p><strong>Key insight: 54% of tools have solid quality but zero community adoption. They're invisible to agents.</strong> The path from C to B is simple: get 10 stars. From B to B+: get 50 stars + stay active. The scoring system tells you exactly what to do.</p> <h2> Check Your Grade </h2> <p>Paste your GitHub repo:</p> <p><strong><a href="https://agent-tool-intel-production.up.railway.app" rel="noopener noreferrer">https://agent-tool-intel-production.up.railway.app</a></strong></p> <p>Then embed your badge:<br> </p> <div class="highlight js-code-highlight"> <pre class="highlight markdown"><code><span class="p">[</span><span class="nv">![Grade</span><span class="p">](</span><span class="sx">https://agent-tool-intel-production.up.railway.app/badge/YOUR_ORG%2FYOUR_REPO</span><span class="p">)</span>](https://agent-tool-intel-production.up.railway.app) </code></pre> </div> <p><em>Agent Tool Intelligence is open source (MIT). <a href="https://github.com/agent-tool-intel/agent-tool-intel" rel="noopener noreferrer">GitHub</a> · <a href="https://agent-tool-intel-production.up.railway.app/scoring/methodology" rel="noopener noreferrer">Methodology</a> · <a href="https://agent-tool-intel-production.up.railway.app/report/monthly" rel="noopener noreferrer">Monthly Report</a></em></p> <p>Tags: <code>#mcp</code> <code>#ai</code> <code>#agents</code> <code>#opensource</code> <code>#typescript</code> <code>#developertools</code></p> ai mcp typescript opensource
