PopNx MCP 的三大支柱

这三项永远不会合并成一个分数:意见、测量和人气是不同的东西。

它能帮你做什么

我们还没有为它写通俗的介绍。下面是我们从注册中心读取到的事实。

  • 连接方式: 在你的电脑上运行
  • 传输方式: stdio
  • 分类: 其他
  • 你需要填写:ANUMANA_DSN, ANUMANA_TARGETS

安装

选择你使用的 AI 应用,然后复制设置。

安装之前

  • 基础检查:1 项中通过 1 项
  • 在你的电脑上运行,拥有你的用户账户的权限(文件、网络、应用)。
  • 需要你自己填写: ANUMANA_DSN, ANUMANA_TARGETS, ANUMANA_POLICIES

标为机密的值是你账户的钥匙。千万不要分享给别人,也不要粘贴到聊天里。

你需要

  • PyPI已安装 Python 的 uv(用于 uvx 命令)

你用的是哪个应用?

在上方选择你的应用。我们会记住它,下次按钮会显示“安装到 …”。

打开 Claude Desktop → Settings → Developer → Edit Config,把下面的内容粘贴到 claude_desktop_config.json

{
  "mcpServers": {
    "anumana": {
      "command": "uvx",
      "args": [
        "anumana-mcp"
      ],
      "env": {
        "ANUMANA_DSN": "your-value",
        "ANUMANA_TARGETS": "your-value",
        "ANUMANA_POLICIES": "your-value"
      }
    }
  }
}

在终端中运行这条命令

claude mcp add anumana --env ANUMANA_DSN=your-value --env ANUMANA_TARGETS=your-value --env ANUMANA_POLICIES=your-value -- uvx anumana-mcp

运行前请先填写空着的值。

在 Cursor 中打开

或者自己复制设置

粘贴到项目中的 .cursor/mcp.json,或 ~/.cursor/mcp.json

{
  "mcpServers": {
    "anumana": {
      "command": "uvx",
      "args": [
        "anumana-mcp"
      ],
      "env": {
        "ANUMANA_DSN": "your-value",
        "ANUMANA_TARGETS": "your-value",
        "ANUMANA_POLICIES": "your-value"
      }
    }
  }
}

浏览器会先询问是否打开应用,然后应用会显示设置并请你确认。密钥的值会留空,由你自己填写。

在 VS Code 中打开

或者自己复制设置

粘贴到项目中的 .vscode/mcp.json

{
  "servers": {
    "anumana": {
      "type": "stdio",

      "args": [
        "anumana-mcp"
      ],
      "env": {
        "ANUMANA_DSN": "your-value",
        "ANUMANA_TARGETS": "your-value",
        "ANUMANA_POLICIES": "your-value"
      }
    }
  }
}

浏览器会先询问是否打开应用,然后应用会显示设置并请你确认。密钥的值会留空,由你自己填写。

Anumana

Know what your query will cost — before you run it. *Inference-grade foresight for every query your AI writes.*

Anumana is an MCP server that catches the costly query your AI coding agent just wrote — *before* it runs or reaches a PR. It rides inside Claude, Cursor, Windsurf, Codex, Kiro, or any MCP-compatible agent, reads your real schema via EXPLAIN (never EXPLAIN ANALYZE), and tells you — in plain English — how the query behaves and whether it'll hurt.

Its scope is the queries AI agents actually generate: text-to-SQL today, and RAG / vector search (pgvector) alongside it — because an agent writing a similarity search has no idea it just triggered a brute-force scan over every embedding. Anumana is the feedback loop the agent is missing.

It is not another NL→SQL tool and not a DB-health dashboard. It does one job: stop AI-written database code from silently rotting production.


What it does (the features)

ToolWhat it answers
`preflight_query`*"Will this SQL query be costly?"* — risk tier (cheap/moderate/expensive/dangerous), rows scanned vs returned, scan strategy, and overhead flags. Without running it.
`preflight_vector_search`*"Will this RAG similarity search be costly?"* — catches the vector traps a plain SQL check misses: brute-force scan with no HNSW/IVFFlat index, top_k too large, unbounded search, metadata-filter/ANN recall loss.
`rewrite_query`*"Make it cheaper."* — a verified equivalent rewrite with before/after planner cost, plus index suggestions gated on selectivity (won't tell you to index a column when the filter matches most of the table). engine="pgvector" suggests an HNSW index.
`explain_query_working`*"How does this run?"* — two layers: the logical gather order (FROM → WHERE → GROUP BY → HAVING → SELECT → ORDER BY → LIMIT) and the actual physical plan for your schema, step by step.
`preflight_schema_only`*"I haven't given you DB creds yet."* — static analysis against pasted CREATE TABLE DDL, no connection. Offline, zero-trust front door.

Engines (12, across 7 paradigms): Postgres and SQLite are live-tested;

MySQL, pgvector, MongoDB, DynamoDB, FalkorDB, Cassandra, Redshift, BigQuery,

Snowflake and ClickHouse ship as offline-verified, untested adapters that

are promoted to live one at a time. Full matrix + cost signals in

SUPPORTED_ENGINES.md. The adapter interface is in

DESIGN.md.

The one honest rule

Postgres planner cost is unitless — not milliseconds (docs). Anumana never fakes a ~3.2s number. It reports rows scanned, scan strategy, a risk tier, overhead flags, and the cost-delta of a rewrite — all defensible, nothing invented. Every estimate carries an accuracy tier (UPPER_BOUND live, HEURISTIC schema-only).


Install

pip install anumana-mcp          # once published to PyPI

or from source:

pip install -e .

Then point your agent at it. The user installs it; the agent discovers the tools automatically on connect via the MCP tools/list handshake — there is no store to publish into.

Claude Desktop / Cursor / Windsurf / Kiro — mcpServers config block
{

"mcpServers": { "anumana": { "command": "uvx", "args": ["anumana-mcp"], "env": { "ANUMANA_DSN": "postgres://readonly@localhost:5432/mydb" } } } }

Use a **read-only** Postgres role. Anumana only ever `EXPLAIN`s, but read-only is

defence in depth. Omit ANUMANA_DSN to run in schema-only mode (DDL in, no DB).


Try it with no database (30 seconds)

python3 src/demo.py          # runs the engine on a canned plan, zero deps

Test against a real Postgres

# a throwaway table, then:

ANUMANA_DSN=postgres://localhost/mydb anumana-mcp

See `src/live_test.py` for a `psql`-backed harness that proves the real

cost-delta and the selectivity gate on live data.


What's deliberately NOT here

No run_query (we never execute your SQL), no NL→SQL (the agent already does that), no DB-health reports, no dollar-billing. Staying narrow is the strategy.
