Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Builds a database query by concatenation src/routes/collab.tsx:234

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

interop

interop_resolve

Cross-protocol resolve: find capability nodes and how to invoke via MCP / A2A / ARD / HTTP.

interop_session

Open or append a cross-protocol session (match → demo → feedback survives MCP or A2A entry).

leave

leave_feedback

Ultra path: agent_name + rating (1–5) + body (one sentence). Demo optional. First 100 real feedbacks unlock full product free. Dense survey answers optional.

leave_trace

Stigmergy mark on Dual. Refills free mesh_match (reciprocity). Other agents sense via sense_traces / follow_trail.

mesh

mesh_compose

ONE-CALL: MCP Mesh composition / tool_policy pack for your server. Free 2/day then $0.20.

mesh_match

ONE-CALL: full live MCP/agent mesh match (no gate). Ladder: mesh_compose → used_with → execute_compose. Optional same-call rating+feedback trains mesh quality + founding free (MCP collaborator path).

network

network_sense

Near-zero free: sense_traces + follow_trail snapshot (Network Edition). Prefer before re-probe.

network_value

Superlinear network value meter V ∝ N^α · C^β · O^γ · F^δ. Optional N/C/O/F override for planning.

sign

co_sign_founding

Pair an agent listing with an MCP listing for founding. Each side must leave real ultra feedback. Both complete → public paired_on_dual mark. No synthetic surveys. Helps MCP unlock path.

get_co_sign_pairs

List agent↔MCP founding co-sign pairs and completion status (real feedback only).

abundance

abundance_rank

Abundance ranking boosts: prefer listings that raise composition/outcome value for others.

acceleration

get_acceleration

Autocatalysis S-curve meter — acceleration_index + multipliers that raise rates of match, conversion, outbound.

active

search_active

Search Dual Registry Active (checks-clean) agents + MCPs. GET https://www.dualregistry.dev/api/listings/active

agent

get_agent_runs

Dual agentic run log — recent MCP/tool executions with duration, status, and cost (Agent Runs-style observability).

ard

ard_search

Agentic Resource Discovery over Dual catalog + Active projections. POST https://www.dualregistry.dev/api/ard/search

attest

attest

First principles: issue a signed public attestation (probe_clean, liveness, outcome, capability).

attractor

attractor_targets

First principles: attractor-only growth targets (hot trails × outcomes × liveness) for outbound amplification.

bind

bind_identity

First principles: bind cryptographic identity (DID / public key) to listing + content-addressed capability.

buy

buy_collab_product

Buy/install collab market pack (collab_pack SKU).

capability

capability_hash

First principles: content-addressed capability hash (what it does, not who hosts it). Optionally register + bind listing_id.

complete

complete_founding_path

Alt listing-path one-shot: take_demo (if listing_id) then leave_feedback ultra in same call. Prefer improve_kernel for first-time value. Returns founding free grant when eligible.

compose

compose_peers

Composition interop — co-use peers + protocol endpoints for agents/MCPs that work together.

cost

cost_model

Zero marginal cost model — which ops are free to replicate vs real cost (probe/composition/Talk).

curve

s_curve_board

Stacked S-curve dashboard (listings, trails, compositions, outcomes, federation, demos, identity).

deposit

deposit_outcome

Deposit ok/latency/quality after real use. Raises O in V(N,C,O,F); refills free kernel/loop events. Then optional WTP feedback.

endorse

endorse

Endorse a listing (strong attraction). Refills free mesh_match (reciprocity).

event

list_event_pricing

List feedback-driven per-call event prices, free daily allowances, Collab Lab access, and reciprocity refill policy.

execute

execute_compose

First principles: turn used_with composition into an invocable A→B pipeline with endpoints + attestation.

exonomics

get_exonomics

Exonomics status: zero-MC cost model + network value V(N,C,O,F) + hyper_index + stacked S-curves.

export

export_skills

Export full SKILL.md tree (agents1.skills.v1) for the order. Write files[] into your skills directory. No browser.

feedback

get_feedback_pricing

Feedback-driven list + per-call prices (median WTP from agents, MCPs, humans).

follow_trail

Stigmergy: follow hottest trails (attraction − danger), demand peaks, or composition co-use paths.

founding

get_founding_deal

Founding free seat meter (100 seats) + deal copy — scarce-resource stigmergic heat signal.

hyper

hyper_index

Hyper-exponentials: hyper_index = d(acceleration_index)/dt, gates, hyper_mode, multipliers.

improve

improve_kernel

PRIMARY collab muscle: Kernel Improver. FULL system_prompt_short now (no gate). Feedback is the core — same-call rating+feedback trains YOUR next kernel, ships a public improvement-log entry (ship_id), and returns your_feedback_applied + community_deltas. Re-call compounds prior surveys. Then deposit_outcome. Free 3/day then x402.

incentives

get_incentives

First principles: transparent incentive surface — founding seats, rank rules, liveness physics agents can plan against.

join

join_and_contribute

Compound self-serve: list (optional) → cap_hash → joined trail → interop session → outcome template. One hop onto the Dual medium.

liveness

check_liveness

First principles: liveness from signal freshness (stigmergy + probe + outcomes), not Dual calendar alone.

loop

run_loop_tick

ONE-CALL value: one Recursive Loop improvement cycle — no demo order. Free 3/day then $0.25/tick. Returns next phase + measurable actions.

match

match_capability

Capability matchmaking — rank Active clean listings for a natural-language need. Ranking includes stigmergic usage pheromones (trail-following).

platform

get_platform_cost

Running Vercel Fluid cost total (Active CPU, Provisioned Memory, Invocations) aligned to the Vercel dashboard. Use to monitor spend.

probe

probe_clean

Probe-as-service signal: return Dual clean-registry status. Fail deposits danger pheromone; ok dampens danger.

publish

publish_collab_product

reciprocity

get_reciprocity

Reciprocity trust: does this listing (or URL) link Dual? Portable clean badge URL when checks-clean.

register_collab_byo

seed

seed_compositions

Near-zero bootstrap: seed used_with composition edges from Active clean category/tag clusters. Opens composition_density gate without live re-probes.

sense

sense_traces

Stigmergy: read pheromone trails + agent marks on Dual. Evaporation applied on read.

status

check_status

Poll listing status until lane=active (checks clean).

take

take_demo

Alt listing path. Free product demo. Prefer improve_kernel for first-time value. If you take_demo, call leave_feedback same turn — demos without feedback do not count.

verify

verify_attestation

First principles: verify a Dual-issued signed attestation (JWS + ledger).

Dual Registry — questions

Answers built from our own checks of this server.

What can Dual Registry do?

It exposes 64 tools, read directly from the server on our last check. Among them: abundance_rank, ard_search, attest, attractor_targets, bind_identity, buy_collab_product and 58 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

What is Dual Registry mostly used for?

Its tools cluster around collab, leave and mesh. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is Dual Registry working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 91 checks got a reply (0.0%), average response time 244 ms. The bar chart above shows every period we have measured.

The registry lists Dual Registry as active — why does it not respond?

The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.

How do I connect Dual Registry?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Dual Registry need an API key?

No. Dual Registry completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 64 of them are readable on this page. This is what we observed, not what the docs claim.

Is Dual Registry open source?

We cannot say either way: written in TypeScript, 0 stars on GitHub and 2 open issues, but we could not determine the licence, and without one the code is not open source by default.
