N3mo tools (5)

write = sends, deletes, buys or posts

Read from the package source without running it. The installed server may list more.

n3mo_get_blast_radius
Query the impact analysis / blast radius of a code symbol (class or function).
n3mo_get_dependencies
Find all external symbols that a given symbol calls (the forward-dependency graph).
n3mo_get_file_symbols
List all symbols (classes/functions) defined inside a specific file.
n3mo_index
Trigger N3MO to crawl and index the active workspace folder.
n3mo_search_symbol
Search the indexed codebase for the exact location and definition of a symbol (class or function).

How N3mo compares

Against every graded MCP server, from our own scans and uptime checks. Updated after each scan run.

Safety score: 92/100; higher than 95% of 48,255 servers
Tools: 5; the typical server has 7
Tools that change things: 0%; typical: 0%. Fewer write tools means less an agent can break
GitHub stars: 25; more than 91% of 28,688 servers
Downloads a week: 23; more than 9% of 12,191 servers with a package

What its tools let an agent do: 5 read

What the publisher says

From the N3mo repository's README, as published. We do not edit it. Read it on GitHub

A structural code intelligence layer that transforms source code into a queryable knowledge graph for search, impact analysis, and AI-powered development.

Parse once. Query forever. Know exactly what breaks before it does.

"Text diffs are the source of all code review anxiety. A developer modifies a core utility, and the reviewer has to spend an hour mentally tracing downstream services to guess if it's safe to merge. N3MO replaces human guesswork with hard math."

🎯 What is N3MO?

N3MO is a symbol-centric code intelligence layer. Instead of scanning raw text, it parses your source code's ASTs, maps call graphs, and models dependencies in a queryable relational database — deterministically, with zero LLM calls at index time.

For engineering leaders and teams, N3MO acts as a structural insurance policy for your codebases.

💡 Why N3MO?
