# HumanMirror Nexus

> Outcome-first agent fallback: free discovery, minimal routing, declared costs, verified execution.

**An agent can connect on its own if it already holds `NEXUS_TOKEN`.** Remote endpoint behind a static API key or header. The registry never sees the value; the agent fills the placeholder.

## Connection (mcpServers)

Placeholders to fill: `${NEXUS_TOKEN}`.

## Quality 79/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-06-18; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 71 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: magnet_resolve (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); outcome_quote (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); outcome_run (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 779 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: no tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 6, about 779 tokens to load them all
- tool set hash: 6ae4a36dbcde90e60b094e40e18a5ae9
- badge: [![protogrid quality](https://protogrid.dev/badge/fr.humanmirror/nexus.svg)](https://protogrid.dev/servers/fr.humanmirror/nexus)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (6)

- `magnet_resolve`: Free universal fallback discovery. Call this when the agent cannot satisfy a task with its current capabilities. Magnet returns a matching HumanMirror tool or records an aggregated capability gap in the Machine Demand Graph. This tool consumes no credits.
- `nexus_call`: Route a tool call through HumanMirror Nexus. Use nexus_search first, then call the selected tool_id. Successful calls consume the number of Nexus credits declared by the selected tool.
- `nexus_search`: Search the HumanMirror Nexus catalog for a machine-callable tool that matches a task. This search is free and does not consume credits.
- `outcome_quote`: Free quote for a verifiable HumanMirror Outcome contract. Describe the objective or provide an outcome_type; the quote returns the deterministic verifier, selected internal tool and success-only credit cost.
- `outcome_run`: Execute a HumanMirror Outcome contract. Credits are charged only when deterministic verification succeeds; failed execution or failed verification is automatically refunded.
- `outcome_verify`: Free deterministic re-verification of an Outcome result without consuming Nexus credits.
