What is 08-mono-repo-mcp?

A set of patterns for searching Snowflake's monorepo, a single repository containing many related projects and millions of lines of code, through GitHub. It uses GitHub API tools to search code and retrieve files without downloading the repository.

Use it to search Snowflake source code, retrieve files, find repositories, and investigate areas such as Snowsight and other web applications.

It avoids keeping a very large local copy while helping an assistant find current source code in targeted searches.

Install

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Clone the repo

git clone --depth 1 https://github.com/sfc-gh-cconner/support-rules-mcp

agentmods

npx agentmods add rules/sfc-gh-cconner/support-rules-mcp/08-mono-repo-mcp

Made for: Cursor.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.03234	$0.03234
Opus 5	$0.01617	$0.01617
Sonnet 5	$0.00647	$0.00647
Haiku 4.5	$0.00323	$0.00323

Security

Grade A, and why

08-mono-repo-mcp scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

PURPOSE: Practical patterns for navigating Snowflake mono repo using GitHub MCP API tools.

🎯 Core Concept

The Snowflake mono repo contains millions of lines of code. GitHub MCP provides API-based access to search and retrieve source code without requiring a local clone (50GB+).

Key Benefits:

No local repository required
Always up-to-date code
5,000 API calls/hour limit
Fast, precise code search

📍 Repository Access

GitHub Repository: snowflakedb/snowflake
Access Method: GitHub MCP API tools

See also: Snowsight and Snowflake web applications in snowflakedb/snapps repository.

🔍 Essential MCP Tools

1. Code Search

mcp_github_search_code(
    query='search terms repo:snowflakedb/snowflake',
    perPage=30,  # Optional: results per page (default 30, max 100)
    page=1       # Optional: page number
)

2. File Retrieval

mcp_github_get_file_contents(
    owner="snowflakedb",
    repo="snowflake",
    path="path/to/file.java",
    ref="main"  # Optional: branch/tag/commit
)

3. Repository Search

mcp_github_search_repositories(
    query='snowflake in:name org:snowflakedb'
)

🎯 Search Strategies

Strategy 1: Error Message Investigation

Step 1 - Broad Search:

mcp_github_search_code(
    query='"exact error message from logs" repo:snowflakedb/snowflake'
)

Step 2 - Narrow by Component:

# If too many results, narrow down
mcp_github_search_code(
    query='"error message" path:GlobalServices/Auth repo:snowflakedb/snowflake'
)

Step 3 - Get Full Context:

mcp_github_get_file_contents(
    owner="snowflakedb",
    repo="snowflake",
    path="path/from/search/results.java"
)

Strategy 2: Component Investigation

Find Component Definition:

mcp_github_search_code(
    query='class NetworkPolicyDPO repo:snowflakedb/snowflake language:java'
)

Find Component Usage:

mcp_github_search_code(
    query='NetworkPolicyManager repo:snowflakedb/snowflake'
)
