Common questions

Is EchoLedger safe?

It passed 0 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.2.3) reached the registry 3 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

echoledger-mcp

EchoLedger's MCP server. Analyze live Uniswap V2/V3, Balancer, and Curve stableswap pools — positions, price moves, pool health, rug signals, slippage, and depeg risk — or build a portable State Twin for off-MCP analysis, from any MCP-compatible AI client. Reads real chain state via a caller-supplied RPC; the endpoint itself is authless.

Endpoint: `https://mcp.echoledger.ai/mcp` (streamable-HTTP, authless).

Smithery

Listed at smithery.ai/servers/ic3moore/echoledger — connect via the Smithery gateway from any supported client.

Tools

The endpoint ships 11 tools over live Uniswap V2/V3, Balancer weighted (2-asset), and Curve stableswap (2-asset) pools. Two surfaces:

10 reactive primitives — one question, one answer, one chain read. Four of them also take a vector input (e.g. price_change_pcts[], amounts_in[]) to sweep a whole grid/curve in one call.
`BuildStateTwin` — returns a portable State Twin (the pool's state as JSON) that a client rehydrates locally to run unlimited counterfactuals off the MCP, zero further RPC.

Every call takes pool_address, rpc_url, and pool_type, plus an optional chain_id guard and block_number pin — nothing is stored. Each reactive tool is protocol-specific and advertises only the `pool_type` values it accepts; pointing one at an unsupported type returns a clean error before any chain read.

Full reference — params, returns, and a verified example per tool: [`docs/TOOLS.md`](docs/TOOLS.md).

Scope: the Balancer tools cover 2-asset weighted pools; the stableswap tools cover 2-asset plain Curve pools (rate-bearing pools — metapools, LSD — are a later release). A stableswap tool pointed at a 3-coin or rate-bearing pool fails cleanly.

Uniswap V2/V3

`AnalyzePosition`

PnL decomposition for an LP position — impermanent loss, fees, and net.

"Analyze my position in the V3 USDC/ETH pool."

`SimulatePriceMove`

"What if price moves X%?" — projected reserves, position value, and IL.

"If ETH drops 20%, what happens to my V3 ETH/DAI position?"

`CheckPoolHealth`

TVL, reserves, LP concentration, and recent activity for a pool.

"Is this V3 pool healthy?"

`DetectRugSignals`

Threshold-based rug flags on a pool's on-chain state.

"Any rug signals on this V2 pair?"

`CalculateSlippage`

Slippage, price impact, and max trade size for a given trade.

"How much slippage on a 50 ETH buy in this V3 pool?"

Balancer (2-asset weighted)

`AnalyzeBalancerLP`

PnL decomposition for a 2-asset Balancer weighted-pool position, using the weighted-pool IL formula where the token weight shapes IL magnitude.

"How is my 80/20 BAL/WETH Balancer position doing?"

`SimulateBalancerMove`

"What if the base token moves X%?" — projected value and IL on a 2-asset weighted pool, weight-aware.

"If BAL drops 30%, what happens to my BAL/WETH Balancer LP?"

Curve stableswap (2-asset plain)

`AnalyzeStableswapLP`

PnL decomposition for a 2-asset Curve stableswap position via the amplified-invariant IL formula — small depegs can produce outsized IL at high A.

"Analyze my position in the crvUSD/USDC pool."

`SimulateStableswapMove`

"What if the peg shifts X%?" — projected value and IL on a 2-asset stableswap pool. At high A, large shocks may be physically unreachable (returned as null).

"What happens to my USDC/DAI Curve LP if USDC depegs 2%?"

`AssessDepegRisk`

IL across a ladder of depeg levels (default 2%, 5%, 10%, 20%, 50%) for a 2-asset stableswap position, with an optional constant-product benchmark.

"How exposed is my crvUSD/USDC position to a depeg?"

State twin builder (all four pool types)

`BuildStateTwin`

Reads a pool once and returns a portable State Twin — the pool's state as JSON (__type__ + fields + a content_hash). A client rehydrates it locally and runs unlimited counterfactuals (price moves, IL, slippage) off the MCP, with zero further RPC — build once, run N. Spans all four pool types. See the twin round-trip in docs/TOOLS.md and the echoledger package.

"Build me a reusable twin of the USDC/ETH 0.05% pool."

*(Honest gap: it's a single-block STATE twin — history-derived health metrics stay server-side reads inside CheckPoolHealth/DetectRugSignals.)*

How it works

echoledger-mcp reads live Uniswap V2/V3, Balancer, and Curve stableswap pool state through a caller-supplied RPC endpoint (BYO-RPC, passed per tool call). The endpoint is authless — no API key, no account. Nothing is logged or stored; each call pulls state, runs the analysis, and returns a typed result.

The analytics are powered by open-source DeFiPy — the same primitives, twin, and tools that run against synthetic recipes, now pointed at real pools. The math is open; the reports are paid.

Roadmap

v0.2 — Balancer & Stableswap live reads ✓ shipped. The 5 Balancer/Stableswap tools went live on DeFiPy 2.2's LiveProviders (2-asset weighted + 2-asset plain Curve).
v0.2.2 — honest schemas, vectors & the twin builder ✓ shipped. Per-tool pool_type enums; vectorized scenario inputs on the four scenario tools; and BuildStateTwin — the 11th tool — for portable, off-MCP twin analysis.
N-asset & rate-bearing pools — 3-asset Balancer, N-coin and rate-bearing (metapool/LSD) Curve, once the upstream DeFiPy primitives extend past 2 assets.
Distribution polish — OCI-package listing, DNS-verified namespace, and OIDC auto-publish.

Develop

python -m venv .venv && source .venv/bin/activate

pip install -e ".[dev]"

Run the server over streamable HTTP (binds to $PORT, default 8080):

PORT=8080 python -m echoledger_mcp.server      # endpoint at http://localhost:8080/mcp

Or over stdio for a local MCP Inspector smoke-test:

python -m echoledger_mcp.server --stdio

npx @modelcontextprotocol/inspector python -m echoledger_mcp.server --stdio

Tests (offline — fake provider + real twin/primitives):
