research-agent

Your long-term research memory — papers indexed, gaps found, reports generated

What is this?

research-agent is a research server for AI agents: it indexes papers (arXiv, Semantic Scholar, local PDFs) into a local SQLite library, and your agent drives it over MCP — ingesting, searching, tracking reading progress, analyzing coverage gaps with its own model, and filing survey reports. No API key required.

The same binary also works as a standalone CLI for terminals and scripts.

Features

	Feature	Why it matters
🤖	MCP server	18 tools your agent drives directly over stdio — no API key needed
🧠	Agent-native analysis	Gap analysis and reports run inside your agent: tools hand over structured state, the agent reasons, results are persisted
🔗	Citation graph	Paper-to-paper reference edges from OpenAlex, forward and reverse, optionally labeled with Semantic Scholar citation intents
📚	Paper indexing	arXiv, Semantic Scholar, OpenAlex, Europe PMC (PubMed), bioRxiv-style preprints, local PDFs, and Zotero (a running instance or its export files)
🔍	Full-text search	FTS5 trigram over title, abstract, notes, tags, keywords and body — works offline
📂	Topic trees	Organize research hierarchically with sub-topics
📖	Reading tracker	Queue, track, and rate what you've read
⚡	Single binary	No runtime, no server — just `research`

Quick Start

Install it as a plugin in your AI agent — no Rust toolchain needed:

Claude Code

claude plugin marketplace add epicsagas/research-agent
claude plugin install research-agent@research-agent

Codex

codex plugin marketplace add epicsagas/research-agent
codex plugin add research-agent@research-agent

Antigravity (agy)

agy plugin install https://github.com/epicsagas/research-agent
agy plugin enable research-agent

Grok Build

grok plugin install epicsagas/research-agent --trust

Hermes Agent

hermes plugins install https://github.com/epicsagas/research-agent
hermes plugins enable research-agent

Hermes loads the root plugin.yaml and register(ctx) in __init__.py. It has no MCP support, so the agent drives research through the bundled skill's CLI commands — install the binary first (brew install epicsagas/tap/research-agent or the curl installer); the SessionStart auto-install hook does not apply to hermes. If skills_guard blocks the install scan, set plugins.scan_on_install: false in the hermes config.

The plugin auto-installs the research binary on session start and exposes 18 MCP tools, so the agent can ingest, search, analyze with its own model, and file reports on its own.

Once installed, ask your agent things like:

"Ingest recent papers on graph neural network training from arXiv"
"What gaps are left in my coverage?"
"Generate a survey report for "

How your agent uses it

The plugin auto-installs the research binary on session start and starts the stdio MCP server (research mcp) — the agent discovers and calls the tools directly; no human typing CLI commands.

Tools (18): init · ingest · index_rebuild · import_papers · paper_body · paper_references · query_papers · topic_brief · gaps_record · list_gaps · report_material · report_save · topics_list · topic_add · state · update_read · papers_missing_keywords · enrich_paper.

Analysis is agent-native: topic_brief and report_material hand over the structured library state (papers, reading progress, recorded gaps, coverage), the agent reasons over it with its own model, and gaps_record / report_save persist the findings. When inspecting text, paper_body accepts an optional query to return anchored evidence snippets (with section and page) instead of the whole body, saving context. No [llm] config or API key is required anywhere in the MCP flow.

Smoke test the server over raw JSON-RPC:

printf '%s\n' \
  '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2025-06-18","capabilities":{},"clientInfo":{"name":"t","version":"0"}}}' \
  '{"jsonrpc":"2.0","method":"notifications/initialized"}' \
  '{"jsonrpc":"2.0","id":2,"method":"tools/list","params":{}}' \
  | research mcp 2>/dev/null

The mcp cargo feature is on by default; build CLI-only with cargo build --no-default-features.

Standalone CLI (secondary)

Prefer driving it by hand? The same binary works as a plain CLI.

# macOS / Linux — pre-built binary, no Rust required
curl --proto '=https' --tlsv1.2 -LsSf \
  https://github.com/epicsagas/research-agent/releases/latest/download/install.sh | sh

# Windows — pre-built binary, no Rust required
irm https://github.com/epicsagas/research-agent/releases/latest/download/install.ps1 | iex

# Homebrew (macOS / Linux)
brew install epicsagas/tap/research-agent

First-run onboarding

Run research init in a terminal and it walks you through the settings that matter: database location, the LLM provider used for gap analysis and reports (the key itself is read from the env var you name, never stored in the file). Local servers (Ollama, LM Studio) are probed for their loaded models so you pick from what actually exists. Re-running it is safe: existing values become the defaults and nothing is reset.

Everything that is configurable shows up in ~/.research/config.toml: options you have not set appear as commented-out lines with their defaults, so the file documents itself. research init --no-onboard skips the prompts (also automatic when stdin is not a terminal, so scripts are never blocked).

Updating

Method	Command
curl installer (macOS/Linux)	Re-run the install script above
PowerShell installer (Windows)	Re-run the install command above
Homebrew	`brew upgrade epicsagas/tap/research-agent`

Verify the installed version:

research --version

Commands

Command	Description
`research init`	Initialize research workspace (interactive onboarding in a terminal: provider, env-var key name; `--no-onboard` to skip)
`research ingest <query> [--source arxiv\|s2\|openalex\|europepmc\|preprints\|all] [--limit <n>] [--topic <id>]`	Ingest papers from arXiv, Semantic Scholar, OpenAlex, Europe PMC (PubMed), or preprint servers (bioRxiv, medRxiv, …); optionally link directly to a topic
`research ingest [--source zotero] [query] [--topic <id>]`	Read papers from a running Zotero over its local API (`ZOTERO_BASE_URL` overrides default endpoint, needs "Allow other applications on this computer to communicate with Zotero" enabled); no query pulls the whole library. Not part of `--source all` — a personal library is not a discovery source
`research ingest --source pdf --path <file\|dir> [--topic <id>]`	Ingest local PDF files (full body text is stored and searchable)
`research import <file\|dir>`	Import BibTeX/BibLaTeX, CSL-JSON, or Zotero JSON files (desktop export or API shape), with abstracts, tags, and normalized DOIs; re-imports skip papers already in the library
`research index [--rebuild]`	Rebuild the FTS search index
`research reingest [--missing-pages]`	Re-extract stored PDF bodies (adds page markers to bodies ingested before they existed)
`research query <q> [--evidence]`	Search papers (FTS5 full-text); `--evidence` also shows the matching body text with its section and page
`research references <id> [--cited-by] [--intents]`	Fetch citation-graph edges from OpenAlex; `--cited-by` reverses the direction, `--intents` labels edges with Semantic Scholar citation intents
`research gaps [--topic <id>]`	Analyze knowledge gaps (CLI: uses `[llm]` if configured)
`research report --topic <id>`	Generate research report (CLI: uses `[llm]` if configured)
`research topics list`	List all topics
`research topics add <name> [--parent <id>]`	Add a new topic (specify `--parent` to create a sub-topic)
`research read <id> [--status <status>] [--rating <1-5>]`	Update reading status or rating
`research read <id> --body`	Print a paper's stored body text
`research status`	Show research state overview
`research export --to zotero [--apply]`	Push paper tags into a running Zotero, matched by normalized DOI. Dry-run by default (prints what would change, writes nothing); `--apply` writes. Items changed in Zotero are skipped, never merged. CLI-only by design — no MCP tool
`research enrich [id] [--keywords "..."]`	Add search keywords to papers so paraphrased queries hit (uses `[llm]` when configured; without one prints the papers needing keywords)
`research dashboard [--port <n>]`	Serve the local web dashboard (read-only views + reading-status editing; loopback by default, token-gated on other hosts)
`research mcp`	Start the stdio MCP server (alias: `serve`)

Verifying the Zotero push needs a running Zotero (10+ for writes): run cargo test zotero_write -- --ignored for the live read, then do one research export --to zotero --apply against a test item and confirm the tag appears in Zotero. Writes pop a per-item confirmation dialog unless you pick "Always Allow" (confirmations are capped at five per minute).

Every subcommand also accepts a global --db <path> flag to use a specific database instead of ~/.research/research.db — useful for isolated or test workspaces.

Requirements

Rust 1.92+ (only if building from source; pre-built binaries need nothing)
Data lives at ~/.research/ (research.db index, config.toml)
Linux binaries target glibc ≥ 2.38 (Ubuntu 24.04+)
Optional: an LLM for research gaps / research report from the CLI only — set [llm] in ~/.research/config.toml (provider, model, api_key_env, and base_url for OpenAI-compatible endpoints); the key is read from that env var at call time. The MCP flow never needs it
Config reference: [dashboard] port (default 7777), plus host and token when you bind beyond loopback — a token is generated into config.toml and required for every request
Optional: research enrich adds search keywords so queries worded differently from the abstract still find the paper. It uses [llm] when set; without one it prints the papers needing keywords, for an agent (or you) to fill in via research enrich <ID> --keywords "...".
