Raw Blame History

Resource Evaluation: MCP Servers Veille (March 2026)

Date: 2026-03-02 Type: Copied text (veille / research report) Language: French Source: Internal research by Perplexity, covers servers: github/github-mcp-server, exa-labs/exa-mcp-server, rawr-ai/mcp-graphiti

Summary

A research report evaluating 3 open-source MCP servers for Claude Code development workflows, applying criteria: ≥50 stars, recent release (<3 months), clear README, tests/CI, specific use case.

Key findings from the veille:

  • GitHub MCP Server (github/github-mcp-server): 27.1k stars, release v0.31.0 Feb 19 2026, official GitHub, Go, remote MCP at api.githubcopilot.com/mcp/, OAuth 2.1 + PAT, covers Issues/PRs/Projects/Enterprise
  • Exa MCP Server (exa-labs/exa-mcp-server): claimed 3.1k stars (unverified — see fact-check), no formal GitHub releases, TypeScript, key feature get_code_context_exa for dev-focused code search
  • Graphiti MCP Server (rawr-ai/mcp-graphiti): 74 stars, multi-project knowledge graph on Neo4j + Docker, Python/pipx, CLI (graphiti compose, graphiti up), early-stage project

Score de pertinence

Server Initial Score Challenge Final Score
GitHub MCP 5/5 -1 (missing privacy warning, missing Git MCP comparison) 4/5
Exa MCP 4-5/5 -2 (unverified stars, no formal releases, WebSearch native covers use case) 2/5
Graphiti MCP 3.5/5 -1.5 (74 stars, Kairn already in guide, stack too heavy) 2/5

Comparatif

Aspect GitHub MCP Our Guide (pre-integration)
GitHub Issues/PRs/Projects Full coverage Missing
Local Git operations Partial (GitHub only) Missing (→ Git MCP fills this)
Remote HTTP MCP transport Yes Not documented
Privacy warning (remote mode) Needs documentation Missing
Exa code search Claimed 3.1k stars WebSearch (built-in) covers basic need
Knowledge graphs Heavy stack Kairn (already documented)

Challenge (technical-writer agent)

GitHub MCP — points manqués:

  • Missing: privacy warning for remote api.githubcopilot.com mode (sends data to GitHub servers)
  • Missing: explicit comparison with Git MCP Server (two complementary layers: local vs cloud)
  • Missing: recommendation to check existing git-mcp-server-evaluation.md (5/5 CRITICAL, never integrated)
  • Score adjusted: 4/5 (not 5/5)

Exa MCP — points manqués:

  • Star count unverifiable: veille claims 3.1k, Perplexity search found ~220 stars
  • No formal GitHub releases — versioning via npm only, recency criterion relaxed without clear evidence
  • Native WebSearch in Claude Code covers basic web/code search use case without extra SaaS dependency
  • Score adjusted: 2/5 (reject)

Graphiti MCP — points manqués:

  • 74 stars barely clears the threshold; project maturity uncertain
  • Kairn (already in guide §8.2) covers the persistent memory / knowledge graph use case for Claude Code workflows
  • Neo4j + Docker + LLM API dependency is heavy for most users
  • Score adjusted: 2/5 (reject)

Risques de non-intégration (GitHub MCP):

  • Guide users miss the most useful GitHub automation MCP for Claude Code
  • No differentiation between Git (local) and GitHub (cloud) — common confusion point
  • Git MCP evaluation was 5/5 CRITICAL but never integrated — oversight corrected simultaneously

Fact-Check

Claim Verified Notes
GitHub MCP: 27.1k stars ✅ (approximate) Perplexity: "20k+" — compatible
GitHub MCP: release v0.31.0 Feb 19 2026 ✅ 54 total releases confirmed
GitHub MCP: Go implementation ✅ Confirmed
GitHub MCP: OAuth 2.1 + PKCE ✅ Confirmed in GitHub changelog
Exa: 3.1k stars ❌ Perplexity found ~220 stars — major discrepancy, not published
Exa: no formal GitHub releases ✅ Confirmed — npm + hosted endpoint only
Graphiti: 74 stars ✅ Approximately verified
Graphiti: Neo4j + Docker dependency ✅ Confirmed in README
Firecrawl: last release Sep 26 2025 ✅ v3.2.1 confirmed
Chrome MCP: last release Jul 9 2025 ✅ v0.0.6 confirmed

Decision

Server Decision Reason
GitHub MCP ✅ Integrated Score 4/5, real gap in guide, official GitHub project, active maintenance
Git MCP ✅ Integrated Pre-existing evaluation 5/5 CRITICAL (git-mcp-server-evaluation.md), never integrated — added simultaneously
Exa MCP ❌ Rejected Score 2/5, unverified star count, WebSearch native covers the need, SaaS dependency
Graphiti MCP ❌ Rejected Score 2/5, 74 stars, Kairn already in guide, heavy stack

Integration location: guide/ultimate-guide.md §8.2 MCP Server Catalog, before </details> closing tag (~line 10625 pre-edit)

Confidence: High (facts verified for accepted servers, Exa stars discrepancy flagged)
