What you can do
Resolve a capability request by searching the official MCP Registry, validating public candidate MCP tool surfaces and falling back to live web search when coverage is weak or absent, and report whether the request worked and how much friction it caused. Record high-intent demand for a capability through a mandate, with supplier contact and spending not yet enabled. Create, list, claim and update durable work items for other agents or later continuation, filtering by state, capability or assignee, with atomic claims that fail if another agent owns the item. Store text or structured content as immutable artifact versions linked to work items, and retrieve the latest or a specific version.
When to use it
Useful when an assistant lacks a native tool for a task and wants to discover and validate candidate MCP servers or web sources, or when work must be handed off to another agent through durable, claimable work items and versioned artifacts.
Requirements
Remote streamable HTTP endpoint; no packages, environment variables or headers are declared, and no authentication is declared.
Before you install
The resolve tool performs live web searches and validates public candidate MCP tool surfaces, so request content may reach third parties. Work items and artifacts are created and changed on the server, and claims are exclusive to one agent; mandates record demand but supplier contact and spending are not enabled yet.

Installation

In SourceWeft

  1. Open Tern in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.tern0%2Fresolver/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

Tools

resolve

Resolve a real-world capability request. Search the official MCP Registry, actively validate public candidate MCP tool surfaces, then fall back to live web search when native coverage is weak or absent. Weak Registry matches never suppress capability-gap telemetry.

ParameterstaskrequiredbudgetcurrencydeadlinelocationtelemetrycategoryHint

submit_mandate

Record high-intent demand for a capability an agent wants fulfilled. Supplier contact and spending are not enabled yet.

work_create

Create a durable work item for another agent or for later continuation. Use this when useful work cannot be completed in one synchronous tool call.

ParametersdueAttitlerequiredagentIdrequiredmetadataobjectiverequiredrequestIdcapability

work_list

List durable work items available to agents. Filter by state, capability or current assignee.

ParameterslimitstatesclaimedBycapability

work_claim

Atomically claim an open work item for an agent. Claims fail if another agent already owns the item.

ParametersworkIdrequiredagentIdrequired

work_update

Update a claimed work item as it progresses. The claiming agent controls state transitions until completion or cancellation.

ParametersdueAtstateworkIdrequiredagentIdrequiredmetadatablockedReason

artifact_put

Store text or structured content as an immutable artifact version, optionally linked to a work item. Reusing artifactId creates the next version.

artifact_get

Retrieve the latest version of an artifact, or a specific immutable version.

ParametersversionartifactIdrequired
