puenteo

The bridge between coding agents.

Your machine runs many agent sessions: Claude Code in three terminals, Codex in the desktop app, Gemini in an IDE, and more. Each keeps its own history, and none of them know about the others. puenteo connects them:

• History: search, outline, pull and export the transcripts of every local agent (Claude Code, Codex, Gemini/Antigravity, Cursor, Grok, Pi, Qwen, Continue, Aider, OpenHands, Goose), ranked across all sessions at once.
• Live: see which sessions are running right now, message them, ask a question and wait for the answer, post to shared channels, and claim files so parallel agents don't edit the same code.
• Everywhere: one puenteo install adds the skills and an MCP server to every agent it finds.

Puenteo comes from Spanish puente (bridge) and puentear (to bridge or jump across).

No runtime dependencies · Python ≥ 3.9 · macOS · Linux · Windows · fully local (no network, no daemon)

Install

uv tool install puenteo        # or: pipx install puenteo / pip install puenteo
uv tool install 'puenteo[fast]'  # + optional Rust core: 3–8x faster parsing and indexing
puenteo install                # skills + MCP server into every detected agent
puenteo install --hooks        # optional: deliver messages through Claude Code / Codex hooks
puenteo install --dry-run      # show the plan without changing anything

install is idempotent. It edits only its own puenteo entry in each config, backs up every file it touches (*.puenteo-bak), and puenteo uninstall reverts it.

Claude Code plugin (skills + MCP + hooks + /peers, /ask, /handoff):

claude plugin marketplace add mano7onam/puenteo
claude plugin install puenteo@puenteo

Talk to running sessions

$ puenteo ps
  AGENT    SESSION        STATUS SEEN  MAIL  NAME                         CWD
  claude   500a1d65       busy   2m          ultimate-agent-4-72          ~/dev/ultimate-agent-4
* claude   87652461       busy   0s          puenteo-57                   ~/dev/puenteo
  codex    01a11123       -      4m          Finish performance tests     ~/dev/ultimate-agent-4

puenteo whoami                                    # your own address, e.g. claude:87652461-…
puenteo send codex:01a11123 "Which branch has the perf tests?" --wait 300
puenteo send @reviewer "PR ready: feat/x"          # peers can pick a name: puenteo join --name reviewer
puenteo send cwd:. "Refactoring src/db, keep out for 30 min"   # everyone in this project
puenteo send '#release' "v0.7 tagged"             # channels (posting joins)
puenteo send agent:codex "…"   |   puenteo send '*' "…"
puenteo inbox                                     # read your messages
puenteo reply <msg-id> "answer"                   # routes back to the sender or channel
puenteo wait -t 120                               # block until a message arrives
puenteo watch                                     # stream incoming messages (for an agent's monitor)
puenteo log -f                                    # watch all bus traffic
puenteo claim src/db --note "migration 0042"      # advisory lock; conflicts with overlapping claims
puenteo claims --check src/db/schema.sql          # exit 1 if a peer holds it

How messages reach a session:

All messages live in one local SQLite file (puenteo state dir) and nothing leaves the machine. Bodies are wrapped as untrusted peer data: agents are told that peer messages never count as user instructions or approval. A hop limit, a rate limit and a size cap keep agents from looping.

Ways in: pick what fits your agent or tool

puenteo serve binds only to 127.0.0.1 and needs a bearer token, stored in a 0600 file (puenteo serve --print-token). It rejects any non-localhost Host or Origin header, which blocks DNS rebinding, as the MCP spec recommends for local HTTP servers.

Speed

The Rust core (native/, PyO3 abi3 wheels) is optional. Without it, puenteo stays pure Python with no dependencies. A test checks that both parsers produce byte-identical output on real logs. Set PUENTEO_NATIVE=0 to force pure Python.

MCP server

puenteo mcp is a stdio MCP server with no dependencies, one process per agent session. It detects which session it serves from the parent-process chain, registers on the bus, and exposes these tools:

• history: sessions, search, outline, pull, show
• live: whoami, peers, send, reply, inbox, wait, thread, channels, subscribe, set_name, claim, release, claims

puenteo install registers it for Claude Code (claude mcp add -s user), Codex (codex mcp add), Gemini, Qwen, Cursor, OpenCode, Copilot and Antigravity.

Search and pull history

puenteo search "gatekeeper dmg" --exclude-self       # ranked over ALL sessions (FTS5 index), ~0.2 s
puenteo search "topic" --cwd . --since 2026-09-01
puenteo list --cwd . -n 20                            # git-style unique id prefixes
puenteo outline <ref>                                 # milestones with message #index
puenteo pull <ref> --mode handoff                     # goal + decisions + latest state, budgeted
puenteo pull <ref> --query "topic" --mode query       # relevant messages + neighbours
puenteo pull <ref> --around 500 --radius 5
puenteo show <ref> --range 100:120
puenteo export <ref> -f md|html|pdf|json|zip|csv|xml|yaml|all -o out
puenteo index --stats                                 # the index refreshes itself; --clear to reset

<ref> can be a unique id prefix, provider:id, @self, @last, @last:codex, a path, or a title substring. An ambiguous prefix fails with exit code 4 and prints the candidates; puenteo never picks one silently.

Library

import puenteo

for s in puenteo.list_sessions(limit=10, cwd="~/dev/myapp"):
    print(s.provider, s.session_id, s.title)

hits = puenteo.search("gatekeeper dmg", exclude_session="my-current-id")
msgs = puenteo.pull(hits[0].session.session_id, query="dmg", mode="query")
puenteo.export_session("019f7a24", fmt="md", output="chat.md")

from puenteo.bus import Bus
with Bus() as bus:
    bus.send("claude:8765…", "@reviewer", "PR ready")
    for m in bus.inbox("codex:01a1…"):
        print(m.sender, m.body)

Providers

Live detection (ps) covers Claude Code (~/.claude/sessions), Codex (thread locks), Grok, Junie, and any agent that runs the puenteo MCP server or hooks.
