Which integrations are available for this server?

Allows querying and searching within git commit history (SHA, author, message, timestamp, parents) ingested from a local repository. Allows querying and searching within GitHub Copilot chat sessions (prompts, responses, attached files) ingested from the local development environment.

How do I use hindsight-mcp?

1. Click on "Deploy Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@hindsight-mcp What have I been working on recently?" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

hindsight-mcp

An MCP server for AI-assisted coding that leverages development history.

Overview

hindsight-mcp consolidates development data (git logs, test results, and GitHub Copilot sessions) into a searchable SQLite database, making it accessible to AI assistants through MCP tool calls in VS Code.

Key Features:

Full-text search across commits and Copilot conversations
Track test results linked to specific commits
Activity summaries and timeline views
Automatic git and Copilot session ingestion

Related MCP server: Memory MCP

Quick Start

Prerequisites

VS Code v1.99+ with GitHub Copilot
cargo-nextest (for test ingestion): cargo install cargo-nextest

Installation

cargo install hindsight-mcp

Configure VS Code

Create .vscode/mcp.json in your project:

{
  "servers": {
    "hindsight": {
      "type": "stdio",
      "command": "hindsight-mcp",
      "args": ["--workspace", "${workspaceFolder}"]
    }
  }
}

Verify Setup

Open VS Code Command Palette (Cmd+Shift+P)
Run "MCP: List Servers"
Confirm hindsight is listed
In Copilot Chat, switch to Agent mode
Ask: "What have I been working on recently?"

That's it! Copilot will use hindsight tools to answer questions about your development history.

MCP Tools

Tool	Purpose	Example Prompt
`hindsight_timeline`	Chronological activity view	"Show recent commits and test runs"
`hindsight_search`	Full-text search	"Find commits about authentication"
`hindsight_failing_tests`	Query test failures	"What tests are failing?"
`hindsight_activity_summary`	Aggregate stats	"Summarise my week"
`hindsight_commit_details`	Commit info with tests	"Details for commit abc123"
`hindsight_ingest`	Trigger data refresh	"Refresh development history"

hindsight_timeline

limit (int): Max events, default 50
workspace (string): Filter by path

hindsight_search

query (string): Search query (required)
source (string): "all", "commits", or "messages"
limit (int): Max results, default 20

hindsight_failing_tests

limit (int): Max tests, default 50
workspace (string): Filter by path
commit (string): Filter by SHA

hindsight_activity_summary

days (int): Days to summarise, default 7

hindsight_commit_details

sha (string): Commit SHA (required)

hindsight_ingest

workspace (string): Path to ingest (required)
source (string): "git", "copilot", or "all"
incremental (bool): Only new data, default true
limit (int): Max items

Test Ingestion

Run tests and automatically ingest results:

# Run all tests and ingest
hindsight-mcp test

# Test specific package
hindsight-mcp test -p my-crate

# Preview without writing to database
hindsight-mcp test --dry-run

The test command automatically:

Spawns cargo nextest with correct flags
Auto-detects the current git commit
Ingests results to the database

For CI pipelines or custom nextest invocations:

# Using stdin mode
NEXTEST_EXPERIMENTAL_LIBTEST_JSON=1 cargo nextest run \
  --message-format libtest-json 2>/dev/null | \
  hindsight-mcp test --stdin

# Using ingest command with explicit commit
NEXTEST_EXPERIMENTAL_LIBTEST_JSON=1 cargo nextest run \
  --message-format libtest-json 2>/dev/null | \
  hindsight-mcp ingest --tests --commit $(git rev-parse HEAD)

Data Sources

Source	Data Collected
Git	Commits (SHA, author, message, timestamp, parents)
Tests	Run metadata, outcomes, durations, failure output
Copilot	Chat sessions, prompts, responses, attached files

Git and Copilot data are ingested automatically. Test results require running hindsight-mcp test.

CLI Reference

  -d, --database <PATH>   Database path [default: ~/.hindsight/hindsight.db]
  -w, --workspace <PATH>  Workspace path [default: current directory]
  -v, --verbose           Debug logging
  -q, --quiet             Errors only
      --skip-init         Skip database init

Environment Variables

Variable	Description
`HINDSIGHT_DATABASE`	Database path
`HINDSIGHT_WORKSPACE`	Default workspace

Database Location

Platform	Default Path
macOS	`~/Library/Application Support/hindsight/hindsight.db`
Linux	`~/.local/share/hindsight/hindsight.db`
Windows	`%LOCALAPPDATA%\hindsight\hindsight.db`

Troubleshooting

Problem	Solution
Server does not start	Check binary path; run with `--verbose`
No data showing	Run `hindsight_ingest` tool via Copilot
Log interference	Use `--quiet` in production
