A network of agentic research specialists coordinated by a principal investigator agent. V1: web-search researcher MCP server + CLI shim.
Adds an operational logging layer separate from the JSONL trace audit logs. Operational logs cover system events (startup, errors, MCP transport, research lifecycle); JSONL traces remain the researcher provenance audit trail. Backend: structlog with two renderers selectable via MARCHWARDEN_LOG_FORMAT (json|console). Defaults to console when stderr is a TTY, json otherwise — so dev runs are human-readable and shipped runs (containers, automation) emit OpenSearch-ready JSON without configuration. Key features: - Named loggers per component: marchwarden.cli, marchwarden.mcp, marchwarden.researcher.web - MARCHWARDEN_LOG_LEVEL controls global level (default INFO) - MARCHWARDEN_LOG_FILE=1 enables a 10MB-rotating file at ~/.marchwarden/logs/marchwarden.log - structlog contextvars bind trace_id + researcher at the start of each research() call so every downstream log line carries them automatically; cleared on completion - stdlib logging is funneled through the same pipeline so noisy third-party loggers (httpx, anthropic) get the same formatting and quieted to WARN unless DEBUG is requested - Logs to stderr to keep MCP stdio stdout clean Wired into: - cli.main.cli — configures logging on startup, logs ask_started/ ask_completed/ask_failed - researchers.web.server.main — configures logging on startup, logs mcp_server_starting - researchers.web.agent.research — binds trace context, logs research_started/research_completed Tests verify JSON and console formats, contextvar propagation, level filtering, idempotency, and auto-configure-on-first-use. 94/94 tests passing.

Marchwarden
A network of agentic research specialists coordinated by a principal investigator agent.
Marchwarden researchers are stationed at the frontier of knowledge — they watch, search, synthesize, and report back what they find. Each specialist is self-contained, fault-tolerant, and exposed via MCP. The PI agent orchestrates them to answer complex, multi-domain questions.
V1: Single web-search researcher + CLI shim for development.
V2+: Multiple specialists (arxiv, database, internal docs, etc.) + PI orchestrator.
Quick start
# Clone
git clone https://forgejo.labbity.unbiasedgeek.com/archeious/marchwarden.git
cd marchwarden
# Install
pip install -e .
# Ask a question
marchwarden ask "What are ideal crops for a garden in Utah?"
# Replay a research session
marchwarden replay <trace_id>
Docker test environment
A reproducible container is available for running the test suite and the CLI without depending on the host's Python install:
scripts/docker-test.sh build # build the image
scripts/docker-test.sh test # run pytest
scripts/docker-test.sh ask "question" # run `marchwarden ask` end-to-end
# (mounts ~/secrets ro and ~/.marchwarden rw)
scripts/docker-test.sh replay <id> # replay a trace from ~/.marchwarden/traces
scripts/docker-test.sh shell # interactive bash in the container
