# woodpecker-mcp

> MCP server that gives an LLM agent (e.g. HolmesGPT) a materialized, queryable service dependency graph in a graph database - deterministic root-cause (deepest failing service), blast radius, and observability blind-spot detection.

**woodpecker-mcp exposes a materialized service dependency graph as an MCP
toolset.** It provides an LLM-based agent such as
[HolmesGPT](https://github.com/robusta-dev/holmesgpt) with a capability those
agents do not retain on their own: a persistent, queryable graph of how services
depend on one another. Root-cause analysis therefore becomes a deterministic
graph traversal rather than a conclusion re-derived on each investigation.

HolmesGPT remains unmodified. It launches woodpecker-mcp as a subprocess (or
connects over HTTP) and discovers the tools it exposes - no fork, custom image,
or plugin is required.

## Why this exists

HolmesGPT markets a "Runtime Dependency Graph", yet its source holds no graph
data structure, no graph database, and no graph-traversal code. Each
investigation infers the relationships on the fly - from traces, Kubernetes
owner-refs, and metric labels - then discards them, and root cause is whatever
the model concludes through a "five whys" prompt. That design is deliberate - it
buys freshness, statelessness, and breadth - but it carries costs that a
materialized graph removes:

| | Holmes (inferred) | woodpecker-mcp (materialized) |
|---|---|---|
| Where relationships live | model context, one investigation | a graph database (FalkorDB) |
| Root cause | reasoned per run (non-deterministic) | deepest-failing-service, one Cypher query (exact, repeatable) |
| Blast radius | re-derived each time | variable-length path traversal |
| Explore it yourself | no | yes (browser UI + Cypher) |
| Blind-spot detection | no | yes |
